SEPARATOR FOR FUEL CELL AND FUEL CELL

PROBLEM TO BE SOLVED: To improve a cooling capacity of a fuel cell while preventing a fuel gas flow channel from being blocked.SOLUTION: Two projection parts 23a of a second separator plate 15 with a low wave part are housed in a recess part 19b of a first separator plate 13 with a high wave part, and both of the separator plates 13, 15 are overlaid. In the two projection parts 23a housed in the recess part 19b of the first separator plate 13, only one of two inclination parts 24a, 24b is in contact with the recess part 19b of the first separator plate 13, and the other inclination part is not in contact with the recess part 19b of the first separator plate 13. A cooling liquid flow channel 25 is formed in a space between the recess part 19b of the first separator plate 13 and the projection part 23a of the second separator plate 15, and an oxidant gas flow channel 27 is formed in a space between the recess part 19b of the first separator plate 13 and a cathode electrode 11 of a membrane electrode assembly 5. A fuel gas flow channel 29 is formed in a space formed between the recess part 23b of the second separator plate 15 and an anode electrode 9.
