PROBLEM TO BE SOLVED: To provide a separator for fuel cell capable of making the cooling water flow uniform within a separator plane. SOLUTION: In a separator 18 for fuel cell having plural cooling water flow passages 26 formed into a different shape, shape of the cooling water flow passage 26 is set so as to make the pressure loss of each cooling water flow passage uniform. The cooling water flow passage 26 is formed of a main flow passage 26a and an auxiliary flow passage 26b, and the main flow passage 26a is positioned in the peripheral part within the separator plane, and the auxiliary flow passage 26b is formed with a restriction part or a bend part 30. |
