Abstract:
A fuel cell that employs a decomposition catalyst on one or more of the membrane, bipolar plates or diffusion media layers in the fuel cell that decomposes hydrogen peroxide, and thus reduces the generation of hydroxyl free radicals. In one embodiment, the decomposition catalyst is ruthenium oxide and is deposited on the structure by various processes, such as chemical vapor deposition process.
