Abstract:
A fuel cell (10) is provided with a flat membrane-electrode assembly (50), a separator (34) and a separator (36) being provided on either side of the membrane-electrode assembly (50). The membrane-electrode assembly (50) has a solid-polymer electrolyte membrane (20), an anode (22), and a cathode (24). The cathode (24) has a cathode catalyst layer (30), a poison-generating layer (31), and a layered body comprising a cathode gas diffusion layer (32). The poison-generating layer (31) has a compound for generating a poison for poisoning the metal catalyst included in the cathode catalyst layer (30) by reacting with hydrogen. Specific examples of poison substances include thiols.
