| 摘要 |
A cell (12) for use in a solid polymer electrolyte fuel cell (10), including a membrane/electrode assembly (18) including a fuel electrode (16a) and an oxidant electrode (16b) disposed on either side of a solid polymer electrolyte membrane (14), the assembly being sandwiched from either side by a first separator (20) and a second separator (22) to give a stacked construction. The first and second separators (20, 22) have a planar shape slightly larger than the solid polymer electrolyte membrane (14), with primary face seal rubber layers (52) being affixed to outer peripheral edge portions of primary faces of the first and second separators (20, 22) superposed against the membrane/electrode assembly (18). Thus, an outer peripheral edge portion of the solid polymer electrolyte membrane (14) projecting outwardly beyond the fuel and oxidant electrodes (16a, 16b) are held clamped fluid-tightly between the first and second separators (20, 22) by means of the primary face seal rubber layers (52) of the first and second separators (20, 22). |
