PROBLEM TO BE SOLVED: To provide a low-cost separator for a fuel cell suppressing the lowering of the conductivity, the dimension error in compacting laminations, and mechanical failure such as output lowering. SOLUTION: A recessed first junction groove 121i individually surrounding air and hydrogen manifolds 121a, 121b, 121d and 121e on the other face of a first plate 121 is formed, and a recessed second junction groove 121j surrounding manifolds 121c and 121f for cooling water and a cooling water channel groove 121h. While a projecting first junction projection 122i individually surrounding air and hydrogen manifolds 122a, 122b, 122d and 122e on the other face of a second plate 122 is formed and a projecting second junction projection 122j surrounding manifolds 122c and 122f of the cooling water and fitting the second engagement groove 121j of the first plate 121. The junction grooves 121i and 121j and the junction projections 122i and 122j are fitted and joined together. |
