PROBLEM TO BE SOLVED: To provide a porous division plate for fuel cell which minimizes structural destruction of a gas diffusion layer or an electrode membrane assembly due to stress concentration, by changing the shape of a flow channel hole formed in the porous division plate.SOLUTION: A porous division plate for fuel cell includes a flow channel plate formed to couple a first contact part in contact with a gas diffusion layer or electrode membrane assembly side, and a second contact part in contact with the cooling water channel side, by a coupling part so that the first and second contact parts come into contact alternately in the longitudinal direction, and a channel hole is formed above the coupling part, so that a part of the inner surface of the channel hole projects toward the center of the channel hole.SELECTED DRAWING: Figure 4 |
