Fuel cell

Abstract

The present embodiment is a fuel cell including at least a membrane electrode assembly including an electrolyte membrane, an anode catalyst layer disposed on one surface of the electrolyte membrane, and a cathode catalyst layer disposed on the other surface of the electrolyte membrane, wherein the cathode catalyst layer includes at least an electrochemical oxygen reduction electrode catalyst including a catalyst metal having oxygen reduction activity and a modifier that modifies the catalyst metal, wherein the modifier is at least one selected from a nitrogen-containing cyclic organic compound and a polymer thereof, and includes a decomposition inhibitor that suppresses decomposition of the modifier in at least one selected from an electrolyte membrane, an anode catalyst layer, and a cathode catalyst layer.
