PURPOSE:To dispense with a separator for separating gas passages and improve the reliability of a fuel cell by arranging adjacent single cells so that electrodes with the same polarity face each other and forming a common gas chamber between them. CONSTITUTION:Adjacent single cells 1 are arranged in a cell stack so that electrodes 4 and 5 with the same polarity face each other, a common gas chamber 9 is formed between them. Crossover leads 14 are extracted from the electrodes 4 and 5 for each single cell 1, single cells 1 are electrically connected to each other via the crossover leads 14. Reaction gas chambers are not required to be separated from each other between the adjacent single cells 1, a separator required for the cell stack with the conventional structure is not required, a flat gas-permeable plate can be used for an electrode substrate in place of a ribbed electrode substrate with a complicated shape. |
