FUEL CELL COMPRISING A PROTON-EXCHANGE MEMBRANE, HAVING AN INCREASED SERVICE LIFE |
摘要 |
A fuel cell includes a proton-exchange membrane, and a cathode and anode fixed on its opposite sides. The anode delimits a flow conduit between a molecular-oxygen inlet area and a water outlet area. The cathode includes a support for catalyst material. The support has first and second materials to which catalyst is fixed, the first material being a graphitized material. The second material has a resistance to corrosion by oxygen that is greater than that of the first material. A quantity of the second material at the inlet area is greater than a quantity of the second material at the water outlet. The cathode comprises a first layer including the first material and a second layer including the second material. A thickness of the second layer decreases between the molecular-oxygen inlet area and the water outlet area. |
