<P>PROBLEM TO BE SOLVED: To provide a membrane electrode assembly for solid polymer fuel cell, having a high initial power generating performance and capable of maintaining stable output characteristics over a long period. <P>SOLUTION: The membrane electrode assembly for solid polymer fuel cell has a cathode and an anode, having a catalyst layer and a polymeric electrolyte membrane arranged between the cathode and the anode. A frame-shape catalyst particulate dispersion layer with a width of 0.1-10 mm is formed on a portion facing the outer periphery of the catalyst layer on one or both the surfaces of the polymer electrolyte membrane so that the outer periphery of the catalyst layer is contained inside the frame of the catalyst particulate dispersion layer. <P>COPYRIGHT: (C)2007,JPO&INPIT |
