摘要： A fuel cell is formed by sandwiching a membrane electrode assembly between a first separator and a second separator. The membrane electrode assembly includes a cathode, an anode, and a solid polymer electrolyte membrane interposed between the cathode and the anode. In the membrane electrode assembly, a catalyst area of an electrode catalyst layer of the cathode and an electrode catalyst layer of the anode terminates at a position spaced upwardly from lower ends of an oxygen-containing gas flow field and a fuel gas flow field.
