Edit time ran out So there is not any info on Breen stations but I think these from EAW could serve as insperation for Breen stations
This is the sum of all Cannon info
Also I know that the Breen use cloaking devices, disruptors, and photon torpedos. The have at least some organic technology. Breen was a planet in the Breen system, homeworld of the Breen species and capital world of the Breen Confederacy. Little was known about it, but it widely believed to be a frozen wasteland. The Breen are a reclusive, powerful, and warlike humanoid race, native to the planet Breen in the Alpha Quadrant. Shrouded in mystery, the Breen were one of the most underestimated races inhabiting the Alpha Quadrant.
Historically, the Klingons were among the first to discover the consequences of underestimating the Breen. During the Klingon Second Empire, Chancellor Mow'ga ordered an entire fleet of Klingon warships to invade and conquer the Breen homeworld. The fleet never returned and was never heard from again.
Even by the 24th century, much was still unknown about the Breen and their otherwise politically nonaligned government, known as the Breen Confederacy. The Federation, however, had limited knowledge of the Breen and was aware of Breen outposts located near a black cluster in 2368. In 2370, the Breen participated in a palio held at Deep Space 3, during which the Ferengi attempted to bribe the Breen pilot into throwing the race. In 2373, the Breen settlements on Portas V near the Demilitarized Zone dealt with the Maquis, supplying them with cold-storage units. It was noted by Ezri Dax in 2375, when captured by the Breen on a planet in the Goralis system, that they were a long way from Breen space.
Other species like the Ferengi had developed closer ties with the Breen by the late 24th century, as both species conducted trade negotiations in 2373. By that same year, the Cardassian Union maintained an embassy on the Breen homeworld.
Breen privateers during the 24th century would often conduct indiscriminate raids against other Alpha Quadrant species. This includes the Breen attack and capture of the Cardassian transport Ravinok in 2366. The survivors of that attack were used for slave labor in the Breen operated dilithium mines on Dozaria. In 2368, Starfleet feared the Breen might have attacked the science vessel SS Vico. Breen privateers also raided the Bajoran colony of Free Haven in 2372; they were, however, successfully driven away by the USS Defiant.
In 2375, the Breen moved from a policy of low-level hostilities toward other major powers to one of open warfare when they allied themselves with the Dominion. They were then allowed access to the Dominion military database. According to the terms of the alliance, the Breen Confederacy received several planets in the Cardassian Union as compensation for joining the war.
Shortly after joining with the Dominion, the Breen attacked Starfleet Headquarters on Earth. A short time later they assisted Dominion forces in breaking the lines at Chin'toka. Under orders from the Female Changeling, the Breen allowed escape pods to carry the Federation survivors to safety. This major battle, known as the Second Battle of Chin'toka, was won by the Dominion thanks to a unique Breen device, a kind of energy dampening weapon which could completely drain all the main power systems of a starship. Both of these defeats dealt a huge blow to the Allies' morale. The only ship immune to the Breen weapon was a Klingon Bird-of-Prey, which serendipitously survived thanks to an adjustment the chief engineer had made to the ship's tritium intermix in the warp core.
Although the Klingon fleet was able to make the needed adjustments against the weapon, the Federation and the Romulans were still unable to defend against the Breen. When the Federation finally did create a defense against the energy dampening weapon, they forced the Dominion fleet to retreat. The Breen official Thot Pran expressed an extreme distaste for surrender, and required the reassurance of the Female Changeling that, instead of surrendering, they were in fact regrouping and attempting to redouble their shipbuilding and replenishment efforts.
With the necessary countermeasures against the Breen's energy dampening weapon obtained, the Federation Alliance was able to go on the offensive once again, choosing to invade Cardassia Prime itself. In hopes of boosting the Breen's will to fight, the Female Changeling offered them control of Earth and Romulus if they succeeded in winning the battle. In the interest of maintaining the alliance, the Breen were positioned ahead of the Jem'Hadar. During the Battle of Cardassia, the Breen were still able to inflict major casualties on the allies, even without the use of their energy dampening weapon. Up to a third of the allies' entire fleet was destroyed during the battle, including the Romulan flagship. The Breen continued to fight for the Dominion until the end of the war, demonstrating a willingness to die for the cause which matched that of the Jem'Hadar. However, when the Cardassian forces switched sides mid-battle, the Dominion and Breen were forced to withdraw to Cardassia Prime. After Odo convinced the Female Changeling to surrender, the Dominion War ended. As allies of the Dominion, the Breen leaders were present during the signing of the Treaty of Bajor.
Physiology
Breen physiology is among the most exotic for humanoid lifeforms, which may be due, in part, to their homeworld's climate. The Breen have no blood or other liquid circulatory system. The Breen brain is structured into four lobes; this protects them from the probing of some empathic species, such as the Betazoids, who are unable to detect the thoughts or emotions of the Breen.
Breen appear physically more resilient than most humanoids. When Worf struck a Breen, the Breen proceeded to incapacitate Worf with a neural truncheon, seemingly oblivious to the assault.
The Breen constantly wear refrigeration suits in order to maintain a cold temperature like that on their homeworld (although Weyoun stated that the Breen homeworld is not a cold wasteland). According to Worf, no outsider had ever seen what a Breen looked like under their refrigeration suits and lived. Even after joining the Dominion, their appearance was unknown to their new allies. Weyoun couldn't help but wonder what they looked like.
The Breen commonly produce offspring at a very early age, at about the equivalence in physical growth of Human third grade children. The Breen entertain their offspring with nursery rhymes. Breen nursery rhymes can be made up of a heterophonic, five-line verse with an alternating tetrameter and pentameter structure. These are nonsensical phrases strung together because they rhyme (at least to the Breen). Some Breen music, which can accompany these nursery rhymes, is written on a Lyxian scale.
The Breen are known to use slave labor; and at least some of these slaves are captured in raids on other species. When the Breen were using Bajoran slaves to mine dilithium ore, there were always at least eight guards within the mines.
The Breen are very prudent when dealing with prisoners. When capturing prisoners, the Breen typically stun them from long range with their disruptors, rather than approaching them and risking close combat. When Worf and Ezri Dax were discovered by the Breen on Goralis while sleeping, the Breen used this technique to subdue them. The Breen feed their prisoners a diet of algae paste, as well as hang them upside down to ensure they cannot escape.
On board starships, the Breen typically send in three guards at a time when they wish to remove a single prisoner from a cell that is being shared with other prisoners. Worf's various attempts at escape always failed, including his attempt to persuade the Breen guards that Ezri was sick, as well as his attempt to short-circuit the door. When Worf attempted to attack the Breen guards, they used a type of neural truncheon to paralyze him. Even after he fell to the ground, partially paralyzed, two Breen guards continued to use the truncheons on him to ensure he would not get back up, before two guards removed Ezri from the cell. In another incident, Worf simply showed signs of anger towards Weyoun and was again shocked by the neural truncheon.
To extract information from captives, the Breen use cortical implants, despite the severe pain and damage it causes to the recipient.
The Breen language is the language spoken by the Breen. To Human ears, it sounds like garbled electronic sounds. Universal translators have to be adjusted in order to properly translate the syntax.
Given that most known humanoid species live on class M planets with an average temperature far above the supposed temperature of Breen, the Breen are largely thought to have had to develop refrigeration suits in order to co-exist with others. However, if the Breen homeworld is temperate as suggested by Weyoun, then their reason for wearing environmental suits, if they were environmental suits at all, was much more mysterious.
The Breen were known for their knowledge of sophisticated cold-storage units, summed up in Captain Sisko's statement, "If anyone knows how to keep things cold, it's the Breen."
Breen warship During the 2360s, the Breen were known for their development of organic technology, which they employed in the construction of their spacecraft. Some of their vessels were even believed to be fitted with cloaking devices. During the mid-2370s, Breen warships utilized energy dampening weapons.
The Breen were known to use type 3 disruptors, like the Romulans and Klingons. The Breen also manufactured a portable hand-held cannon, the CRM 114. It was designed to target moving objects and surface emplacements. It was among the weapons dealt by the Ferengi arms dealer Gaila in the mid-2370s.
The Breen made use of memory probing technology in the form of cortical implants and neural truncheons for subduing prisoners.
Background
■When the Breen helmets were being designed for "Indiscretion", it was decided that they would give viewers the suggestion of a snout, like that of an Arctic Wolf. (Star Trek: Deep Space Nine Companion)
■Some of the actors and stunt performers to have worn the Breen costumes are Cathy DeBuono, Todd Slayton, Max Omega, Wade Kelly, Dennis Madalone, and Tom Morga.
■The Breen costume worn by Dennis Madalone is also labeled "M. Yamasaki".
■Executive Producer Ira Steven Behr has said that the Breen's distinctive, scratchy voice was inspired by the guitar feedback on Lou Reed's album "Metal Machine Music". (Star Trek: Deep Space Nine Companion)
■The model for the Breen helmet closely resembles the Ubese Bounty Hunter suit that Princess Leia wore to Jabba the Hutt's Palace in Star Wars Episode VI: Return of the Jedi.
Now based on that Information I have a few thoughts of my own. Deductions really based on my person knolegde of our own star system and how the veried conditions would likly effect the evolution of a humaniod life form.
1) While the Breen are stated to come from a Earth type planet in a deep freeze state this is highly unlikly to produce the a physiology the requiers refrigerated enviromental suits to sustain life in Earth normal conditions. It is far more that the Breen infact evolved on an erath sized moon orbiting a super giant Jovian type planet of Brown Dwarf star far outside the goldilocks zone of the primary star. This moon would likly have enviromental conditions simalar to Titan. This means that instead of what as a fluid componet of their body they likly have liquid methane based body fluids. Since methane would instanly vapories in earth normal conditions this would lead to wounded Breen leaving no blood trail and to the assumption that they have no body fluides of any kind. Also a methane based physialogy would react extremely combustably with energy weapons further eleminating and obscuring anitomical evidence.
2) The enviromental conditions needed to suport the Breen do not react well with most formes of convetional heat generating technology. This means that the organic compenet of Breen starships and tations is most likly to be the interface between the crew and the rest of the nonorganic ship systems. The need to create what is essentially 2 diametricly opposed envrioments; 1 for the survival and comfort of the crew and the other for most efficient opperation of the ships systems; would be best ocomplished by such an engeneried bio-construct.
3) It is possible that the Breen did not develope to their current levle of development completly on their own. since they appear to use conventional technology dispite it being inmecurial to there very existance I hypothosize that like the Klingons, the Breen where at sompoint in their past conquered and subjigated and they obtained the basis for their curent technology from the invaders when they kicked them out. This would explain Breen technology is not radically different from other Alpha and Beta quadrent powers like the Klingons and Romulans.

Shocking I know but I think they really keep the Breen fell to them even if they are a little overboard compared to the series.
