摘要： A fuel cell or a fuel cell stack component comprises an active area and a non-active area. A peroxide decomposing metal compound or metal alloy is disposed in or on the non-active area of a fuel cell or a fuel cell component. The metal compound or alloy is capable of providing a peroxide decomposing metal species that can migrate from the non-active area to an active area of a fuel cell. A fuel cell or membrane electrode assembly having a peroxide decomposing metal compound or alloy disposed in its non-active area exhibits improved durability.

摘要： An ion exchange membrane is prepared from a block copolymer comprising a hydrophobic polymer segment and a polar polymer segment. The ion exchange membrane is formed by placing a film layer in steam, water or an electric field at a temperature greater than about 40° C. for sufficient amount of time to develop a bicontinuous morphology. The ion exchange membrane is also formed from a film layer comprising a block copolymer and a solvent. The film layer is placed in an electric field at an elevated temperature and dried therein. The film layer is thereby converted into an ion exchange membrane with bicontinuous morphology. The ion exchange membrane prepared according to these processes exhibits improved mechanical and electrochemical properties.
