<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of preventing dew condensation of reaction product water in an electrode surface as soon as possible with a simple structure, so as to secure excellent power generation performance. <P>SOLUTION: The fuel cell 10 includes an electrolyte membrane-electrode assembly 12, and a first and a second metal separators 80, 16 pinching the electrolyte membrane-electrode assembly 12. On the first metal separator 80, first flat parts 82 and second flat parts 84 in contact with a cathode side electrode 30 are alternately fitted, concave parts 86 between the first flat parts 82 and the second flat parts 84 functions as oxidant gas flow channels 36. Each second flat part 84 is structured shorter, being compared with the first flat part 82. <P>COPYRIGHT: (C)2010,JPO&INPIT |
