Abstract
A solid polymer fuel cell () has an electrolyte membrane (), and an air electrode () and a fuel electrode () that closely contact to opposite sides of the electrolyte membrane () respectively. The electrolyte membrane () has a membrane core () comprising a polymer ion-exchange component, and a plurality of phyllosilicate particles () that disperse in the membrane core () and are subjected to ion-exchange processing between metal ions and protons, and proton conductance Pc satisfies Pc>0.05 S/cm. Owing to this, it is possible to provide the solid polymer fuel cell equipped with the electrolyte membrane () that has excellent high-temperature strength and can improve power-generating performance.
