Abstract
A solid polymer electrolyte fuel cell includes a solid polymer electrolyte membrane and a fuel cell electrode. The solid polymer electrolyte membrane and/or the fuel cell electrode can contain at least one catalyst selected from oxide catalysts, macrocyclic metal complex catalysts, transition metal alloy catalysts and inorganic salt catalysts. The catalyst decomposes hydrogen peroxide formed during fuel cell operation and prevents the hydrogen peroxide from decomposing the solid polymer electrolyte membrane. As a result, a solid polymer electrolyte fuel cell is formed that is excellent in durability and available at a reduced cost.
