Abstract
A membrane electrode assembly for a fuel cell and a fuel cell employing the same. The membrane electrode assembly includes: a cathode; an anode; and a polymer electrolyte membrane that is interposed between the cathode and the anode, and comprises a proton conductive polymer that is doped with acid to a doping level of less than 200 mole %. The membrane electrode assembly for the fuel cell exhibits an improved efficiency of performance when acid is doped in the polymer electrolyte membrane at a doping level of less than 200 mole. In addition, the performance of the fuel cell can be optimized by separately adjusting the amount of acid doped in the cathode and anode. The fuel cell employing the membrane electrode assembly can be operated at a high temperature in a dry environment and exhibits an improved power generating performance.
