Abstract
A fuel cell includes a plurality of cells. Each cell has a three-layer plate member having an electrolyte layer, an oxygen electrode attached to one face of the electrolyte layer and a fuel electrode attached to the other face of the electrolyte layer. The cell also has a separator affixed only to the oxygen electrode and an oxygen-containing gas flow passage formed between the oxygen electrode and the separator. A plurality of fuel flow passages are formed between an adjacent pair of the cells as assembled. First and second partition wall members are respectively disposed tightly adjacent a pair of opposed end faces of the cell to which faces the oxygen-containing gas flow passage is closed by the separator. Third and fourth partition wall members are respectively disposed along a pair of opposed cell edge portions where the oxygen-containing gas flow passage is open between the pair of cells. The first and second partition wall members have end portions thereof projecting relative to the cell. The third and fourth partition wall members have end portions thereof projecting relative to the cell and placed in tight overlapping contact with the end portions of the first and second partition wall members.
