Fuel cell

摘要

A fuel cell ( 10 ) is formed by sandwiching a membrane electrode assembly ( 14 ) between first and second separators ( 16, 18 ). An oxygen-containing gas supply passage ( 20 ) extends through the fuel cell ( 10 ) in a stacking direction. The oxygen-containing gas passage ( 20 ) includes first and second straight sections ( 20 a , 20 b) to form a single opening. The first and second straight sections are elongated in directions indicated by arrows B and C around a corner at an upper portion of one end of the first separator ( 16 ).
