Abstract:
1. A solid polymer electrolyte fuel cell comprising: a plate-shaped electrode structure ( 7 ); and first and second separators ( 8 , 9 ) that sandwich the electrode structure ( 7 ); the electrode structure ( 7 ) comprising a solid polymer electrolyte membrane ( 10 ); first and second electrode layers ( 11 , 12 ) that sandwich the solid polymer electrolyte membrane ( 10 ); and first and second diffusion layers ( 13 , 14 ) that are disposed outside the corresponding electrode layers ( 11 , 12 ); the first separator ( 8 ) forming, in cooperation with a face on the first diffusion layer ( 13 ) side of the electrode structure ( 7 ), a first gas passage (P H ), one type of gas (H) among a fuel gas (H) and an oxidizing gas (A) flowing through the first gas passage (P H ); and the second separator ( 9 ) forming, in cooperation with a face on the second diffusion layer ( 14 ) side of the electrode structure ( 7 ), a second gas passage (P A ), the other type of gas (A) among the fuel gas (H) and the oxidizing gas (A) flowing through the second gas passage (P A ); characterized in that the solid polymer electrolyte membrane (
