<P>PROBLEM TO BE SOLVED: To provide a fuel cell separator capable of preventing exhaustion and/or back flow of water produced in a power generation region of the fuel cell. <P>SOLUTION: (1) The fuel cell separator 18 has gas passages 27, 28, gas manifolds 30, 31, and a communication passage 34 on a cell surface, the lower end part (a part corresponding to a manifold lower part in an attitude making the cell surface parallel to the gravity direction of produced water) of at least outlet side manifolds 30B, 31B of the gas manifolds 30, 31 is extended to the lower part than a lower surface 34a (a surface corresponding to the lower surface of the communication passage in an attitude making the cell surface parallel to the gravity direction of produced water) to form an extension part 35. (2) The surface corresponding to the lower surface 34a of the communication passage in an attitude making the cell surface of the peripheral parts of the communication passage parallel to the gravity direction of the produced water is formed so as to be low toward the outlet side gas manifolds 30B, 31B from the gas passages 27, 28. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
