<P>PROBLEM TO BE SOLVED: To provide a porous carbon sheet in which the occurrence of wrinkling is prevented over the peripheral part of the porous carbon sheet, and a method for manufacturing the porous carbon sheet in a firing step when manufacturing the porous carbon sheet using carbon fibers, and to provide a membrane electrode fusion product exhibiting stable performance using the porous carbon sheet. <P>SOLUTION: The method for manufacturing the porous carbon sheet includes a step of obtaining a molded article by stacking one or a plurality of sheets of prepregs of a sheet shape composed of at least carbon fibers and a thermosetting resin, and a firing step of carbonizing the thermosetting resin by firing the molded article at 2,000 to 2,700 °C, in which the firing step is performed after trimming the end of the molded article. <P>COPYRIGHT: (C)2009,JPO&INPIT |
