Fuel cell

Abstract

A fuel cell comprising a cathode catalyst layer (2) containing a cathode catalyst particle and a proton conductive resin, an anode catalyst layer (3) and a proton conductive membrane (6) provided between the cathode catalyst layer (2) and the anode catalyst layer (3), wherein a content of the cathode catalyst particle in the cathode catalyst layer (2) is substantially the same on a first surface facing the proton conductive membrane (6) and on a second surface opposite to the first surface, and a content of the proton conductive resin in the cathode catalyst layer (2) is increased with an increase in distance from the second surface toward the first surface.
