HYDROGEN-POWERED FUEL CELL

WIPO Patent Application WO/2011/078310

A1

Disclosed is a solid polymer electrolyte having excellent durability, which is suitable for use in a solid polymer fuel cell that is capable of stably generating power over a long term. Specifically disclosed is a hydrogen-powered fuel cell, which is characterized by comprising a solid polymer electrolyte membrane that is sequentially provided with a positive electrode catalyst layer, a gas diffusion layer and an oxygen gas channel on one surface, while being sequentially provided with a negative electrode catalyst layer, a gas diffusion layer and a hydrogen gas channel on the other surface. The hydrogen-powered fuel cell is also characterized in that the solid polymer electrolyte membrane contains a polymer having a sulfonic acid group and at least one kind of tin component selected from among tin ions and tin compounds.
