<P>PROBLEM TO BE SOLVED: To improve on distribution efficiency of reaction gas in a porous body layer with airtightness maintained. <P>SOLUTION: A sealing gasket 30 is integrally molded with a MEGA 25, porous body flow channel layers 28, 29, as fluororubber as a material of the sealing gasket 30 gets impregnated with pores of gas diffusion layers 23a, 23b and the porous body flow channel layers 28, 29. In this implementation, pores at a resin impregnation area 15 of the porous body flow channel layers 28, 29 are impregnated with silicon-group resin. That is, due to jamming, the fluororubber as the material of the sealing gasket 30 is prevented from getting impregnated in an area further inside of the resin impregnation area 15. <P>COPYRIGHT: (C)2007,JPO&INPIT |
