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： The present invention is directed to addressing performance issues attributable to membrane electrode assemblies, and the components thereof, in electrochemical conversion cells. In accordance with one embodiment of the present invention, a device comprising at least one electrochemical conversion cell is provided. The cell is configured to convert first and second reactants to electrical energy and comprises a membrane electrode assembly and at least one membrane reinforcement layer. The combination of elastic modulus and thickness of the reinforcement layer and the bond between the reinforcement layer and the membrane electrode assembly are sufficient to enhance the structural integrity of the membrane electrode assembly beyond the operational degradation threshold of the assembly.
