A manufacture comprising a fuel cell, said fuel cell comprising a proton-exchange membrane, a cathode fixed on a first side of said proton-exchange membrane, and an anode fixed on a second side of said proton-exchange membrane, wherein said anode delimits a flow conduit between a molecular-oxygen inlet area and a water outlet area, wherein said cathode comprises a support for said catalyst material, wherein said support for said catalyst material comprises a first material to which catalyst is fixed and a second material to which catalyst is fixed, wherein said first material comprises a graphitized material, wherein said second material has a resistance to corrosion by oxygen that is greater than a resistance to corrosion by oxygen of said first material, wherein a quantity of said second material at said molecular-oxygen inlet area is greater than a quantity of said second material at said water outlet, wherein said cathode comprises a first layer including said first material and a second layer including said second material, and wherein a thickness of said second layer decreases between said molecular-oxygen inlet area and said water outlet area.
