PURPOSE:To lower density of generated current, decrease fuel concentration lowering rate of a current and equalize distribution of current density. CONSTITUTION:A cathode electrode 1 and an anode electrode 2 are provided in both sides of electrolitic plates 10, 11, 10 of multilayer structure and a collector is provided in the side of separator 20 of electrode. The externally supplied fuel and oxidizing agent are supplied to the gas routes 22, 23 of separator 20 through the maniholds 21, 12 of electrolytic plates. While, these are passing through the routes, electro-chemical reaction is generated at the interface of electrode and electrolitic substance, generating electrical power. The intermediate layer 11 of electrolitic plate is composed of four thin tiles of electrolitic plate in different ion conductivity having different gap coefficient or bending curvature of porous material and it is held from both sides by electrolitic plates 10 having uniform ion conductivity. As a result, ion conductivity of electrolitic plate becomes larger than that in the output side of route and density of generated current can be lower than the average value at the input side of route. |
