摘要：A cathode catalyst layer used for a polymer electrolyte fuel cell that includes an electrolyte membrane is provided. The cathode catalyst layer comprises a catalyst having weight of not greater than 0.3 mg/cm2 of a reaction surface of the cathode catalyst layer that is adjoining the electrolyte membrane; and an electrolyte resin having oxygen permeability of not less than 2.2*10−14 mol/m/s/Pa in an environment of temperature of 80 degrees Celsius and relative humidity of 50%.
