To improve the performance of a catalyst layer for a fuel cell, the weight ratio of a hydrogen ion conductive polymer electrolyte and electroconductive carbon particles in a catalyst layer is controlled to satisfy the formula (1): Y=a . logX-b+c where, log represents natural logarithm, X represents the specific surface area of the electroconductive carbon particles (m<2>/g), Y=(the weight (g) of the hydrogen ion conductive polymer electrolyte)/(the weight (g) of the electroconductive carbon particles), a=0.216, c=+/-0.300, b=0.421 at an air electrode and b=0.221 at an fuel electrode. <IMAGE> |
