PROBLEM TO BE SOLVED: To provide a separator unit for a fuel cell capable of reducing the time for building a unit cell and a stack structure while ensuring enough room where a fuel gas, an oxidation gas and cooling water are supplied to by using a separator made of metal thin plate members.SOLUTION: A fuel gas flow distribution plate 53 and an oxidation gas flow distribution plate 51 are made of metal thin plate members. Wave-like parts 81, 81, ... that form a fuel gas room are formed on a plane part on the side of MEA 55 of the fuel gas flow distribution plate 53. First wave-like parts 61, 61, ... that form an oxidation gas room are formed on a plane part on the side of MEA 55 of an oxidation gas flow distribution plate 51. A seal plate 52 made of a frame-shaped thin plate member is laminatedly arranged between the side opposed to MEA 55 of the fuel gas flow distribution plate 53 and the side opposed to MEA 55 of the oxidation gas flow distribution panel 51. A plurality of holes for cooling water passages are formed on the seal plate 52. The fuel gas flow distribution plate 53, the second oxidation gas flow distribution plate 51 and the seal plate 52 are fixed and held in a laminated state. |
