<P>PROBLEM TO BE SOLVED: To prevent excessive load on a solid polymer electrolyte membrane positioned in a resin-impregnated portion when a fuel cell is fastened, and to reliably prevent a decrease in durability of the solid polymer electrolyte membrane. <P>SOLUTION: A fuel cell 10 includes: an electrolyte membrane/electrode structure 12 that has a cathode electrode 20, and an anode electrode 22, that sandwich a solid polymer electrolyte membrane 18 therebetween; and a cathode separator 14, and an anode separator 16, that sandwich the electrolyte membrane/electrode structure 12 therebetween. The electrolyte membrane/electrode structure 12 has a power generation section 46 and a resin-impregnated-portion periphery section 48. On an outer peripheral edge thereof having contact with the electrolyte membrane/electrode structure 12, the cathode separator 14 has a depression 14c that houses the resin-impregnated-portion periphery section 48. On an outer peripheral edge thereof having contact with the electrolyte membrane/electrode structure 12, the anode separator 16 has a depression 16c that houses the resin-impregnated-portion periphery section 48. <P>COPYRIGHT: (C)2013,JPO&INPIT |
