PURPOSE:To improve the current collecting efficiency and the absorption rate of internal stress of a fuel cell, so as to improve the performance, by making the wire diameter of a heat-resisting metallic mesh, the finer at the layer the closer to a fuel electrode. CONSTITUTION:A mesh 7 is divided into several sections on the plane by dividers 10, and it has the area to cover all the surface of the fuel electrode of a unit cell. The wire diameter of the mesh 7 is made finer at the layer near the fuel electrode of the unit cell, and composed of a rough meshwork with the larger wire diameter at the other layers. When the wire diameter of the mesh is fine, the meshwork is made smaller, and the mesh contacts closely to the electrode so as to increase the conductivity and improve the current collecting efficiency. And since the wire diameter is large at the mesh near a separator, the meshwork is made larger so as to facilitate the ecconomy. |
