PURPOSE:To keep contact between an electrode and an electrolyte plate good even if the thickness of the electrode is decreased by arranging adjacent gas channels of a unit cell so that their projections are shifted each other, and assembling the cell with a separator elastically deformed by projections. CONSTITUTION:A gas channel 33 has a plurality of projections 33a whose tips are in contact with a separator 31 on the surface of a plate and its flat part 33b is in contact with a positive electrode 27. A gas channel 35 has a plurality of projections 35a whose tips are in contact with the separator 31 and its flat part 35b is in contact with a negative electrode 29. The gas channel 33 and the gas channel 35 are arranged so as to shift each other. The total thickness of the electrode 27 (29) and the gas channel 33 (35) is slightly thicker than the thickness of a holder 37. When a cell is assembled, the separator 31 is elastically deformed in wave form by projections 33a, 35a. The electrodes 27, 29 and the channels 33, 35 are elastically supported between electrolyte plates 25, 25. |
