PURPOSE:To prevent the change of the porosity of an electrode, the deformation of a gas passage, and the decrease of the contact face pressure by closely sticking porous corrugated sheets having rigidity higher than that of a rib to the rib faces of ribbed anode and cathode electrodes and using the recesses of these corrugated sheets as an anode gas passage and a cathode gas passage respectively. CONSTITUTION:Porous corrugated sheets 8 having rigidity higher than that of a rib are closely stuck to the rib faces of ribbed anode and cathode electrodes 5, 6, and the recesses of these corrugated sheets 8 are used as an anode gas passage 3 and a cathode gas passage 4 respectively. Thereby, the porous corrugated sheets 8 having rigidity higher than that of a rib are closely stuck to the rib faces of the ribbed anode and cathode electrodes 5, 6, and the recesses of these corrugated sheets 8 are used as the anode gas passage 3 and the cathode gas passage 4 respectively, thus the collapse of the electrodes 5, 6 and the deformation of the gas passages 3, 4 is prevented, and a fuel cell preventing the change of the porosity of the electrodes 5, 6, the deformation of the gas passages 3, 4, and the decrease of the contact face pressure cen be obtained. |
