Abstract

A gas passage (28) is formed by stacking a first expand metal member (30) and a second expand metal member (31). The directions in which the major axes of meshes extend differ by 90 degrees between the first expand metal member (30) and the second expand metal member (31). The reaction gas impinges on bond portions (302) of the first expand metal member (30) and strand portions (311) of the second expand metal member (31), while flowing through openings (303) of the first expand metal member (30), and openings (313) of the second expand metal member (31) in the plane direction. Due to such impingement, the reaction gas flows in the normal-line direction, thereby diffusing into an MEGA (25). The difference in the directions of the major axes minimizes formation of partition walls, which would occur if the meshes of the successive expand metal members coincide with each other. Accordingly, the gas flows more efficiently and the fuel cell generates electric power more efficiently.
