  • Fuel cell including fluid-permeable members of differing thermal resistances with respect to an electrolytic membrane
    Patent number: 8568939
    Abstract: A fuel cell includes a membrane-electrode assembly, passageways provided on both sides of the membrane-electrode assembly, and fluid-permeable members provided between the membrane-electrode assembly and the passageways. Thermal resistance of the fluid-permeable member on an anode side is lower than that of the fluid-permeable member on a cathode side. In this case, heat flux at the anode side fluid-permeable member is increased, and heat flux at the cathode side fluid-permeable member is decreased.
    Type: Grant
