PROBLEM TO BE SOLVED: To prevent a reaction gas from permeating to the outside as further as possible in simple configuration.SOLUTION: In a second metal separator 18, an inner seal member 48b with a rectangular cross section is disposed at a position overlapped with an outer edge of a first resin frame member 58 in a direction of lamination. In a first metal separator 14, on the other hand, an outer seal member 46b with a rectangular cross section is disposed outside of the first resin frame member 58 and at a position overlapped with the second separator 18 in the direction of lamination. A seal width h4 of the outer seal member 46b is set to a larger dimension than a seal width h3 of the inner seal member 48. |
