<P>PROBLEM TO BE SOLVED: To uniformly distribute reaction gas into a reaction gas channel which communicates to an inlet buffer portion and an outlet buffer portion; and to keep good power generating performance with simple constitution. <P>SOLUTION: In a fuel cell 10, an electrolyte film/electrode structure 14 is sandwiched between a first separator 16 and a second separator 18. A fuel gas channel 44 is formed on the second separator 18. To an inlet side of the fuel gas channel 44, an inlet butter portion 46 is communicated, and to an outlet side of the fuel gas channel 44, an outlet buffer portion 48 is communicated. The depth of the inlet buffer portion 46 is set to be larger than the depth of the outlet buffer portion 48. Therefore, a pressure loss of the inlet buffer portion 46 is set to be smaller than a pressure loss of the outlet buffer portion 48. <P>COPYRIGHT: (C)2012,JPO&INPIT |
