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.
