<P>PROBLEM TO BE SOLVED: To improve cooling efficiency by a simple structure in a fuel cell system which cools unit cells by utilizing air supplied to the air electrode sides. <P>SOLUTION: A separator 10B of the fuel cell system, which is pinched between unit cells 10A to form a cooling space A, between the unit cells 10A each in which an electrolyte 11 is interposed between electrodes 12, 13, is provided with a porous heat-dissipating plate 14 abutting against the electrodes 12, 13 of the unit cells 10A. Since the contact area of the heat-dissipating plate 14 and the supplied air is enlarged by the pore formation, the function as a heat-dissipating fin to transfer the heat of the electrodes 12, 13 to the air flow flowing in the cooling space A is improved. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
