| 摘要 |
An object of the present invention is to reduce the amount of hydrogen gas permeating an electrolyte membrane to inhibit cross leak, in which hydrogen reacts with oxygen to thermally degrade the membrane, while improving the mechanical strength of the fuel cell to increase its durability and lifetime. The present invention provides a fuel cell reinforcing electrolyte membrane reinforced by a porous membrane, wherein noble metal carrying carbon is present on a surface of and/or in pores in the porous membrane, said membrane being covered by electrolyte layers. |
