PROBLEM TO BE SOLVED: To obtain a successively stable solid high polymer fuel cell stack in which a seal failure and pressure loss increase of gas can be prevented, and in which an inhibition of deterioration of polymer membrane becomes possible. SOLUTION: In a separator 11, on the face opposed to electrode 2b, gas passageway 15 is formed diverging from open hole 13, 14. SUS plate 16 to wrap up gas passageway 15 is arranged on bifurcation minute of open hole 13 and 14 on gas passageway 15. The shape of SUS plate 16 is based on rectangle shape and installed ear part 19 in 2 places, and the ear part 19 in inserted in grade part 18 of separator 11. SUS plate 16 has high rigidity to electrode counter face of separator 11, and the thickness is 50 μm which is thinner than electrode 2b. |
