PURPOSE:To seal electrolyte in a cell and to prevent power loss caused by liquid short between unit cells and electrolyte leakage by installing molecular sieving barrier walls between fuel chambers and fuel passages to prevent electrolyte leakage. CONSTITUTION:Fuel electrodes 1, 11,... are faced to oxidizing agent electrodes 2, 21,... with barrier walls 3, 31,... interposed respectively, and fuel chambers 4, 41,... and oxidizing chambers 5, 51,... are attached thereto. Fuel is supplied to fuel chambers 4, 41,... from a main passage 8 through supply passages 6, 61,..., and exhausted to a main passage 9 through generated gas exhaust passages 7, 71,.... Molecular sieving barrier walls 10, 101,... and 103, 104,... comprising porous filter are installed in supply passages 6, 61,... and gas exhaust passages 7, 71,... respectively. Ion conductive liquid short between unit cells is eliminated to prevent electric power loss, and damage caused by leakage problem is minimized. |
