<P>PROBLEM TO BE SOLVED: To use an antifreeze solution as a cooling liquid in a fuel cell provided with a separator of a porous body. <P>SOLUTION: A second face 22b of a cathode separator 22 is provided with the cooling liquid flow passage forming part 226 in the high-order region UA of a dense part, and a cooling gas flow passage forming part 227 in the low-order region LA containing a porous part 40. The cooling liquid flow passage forming part 226 is communicated with a cooling liquid supply manifold forming part 223a and a cooling liquid discharge manifold forming part 223b, and the fuel cell 10 is cooled by liquid-cooling. The cooling gas flow passage forming part 227 is communicated with a cooling gas supply manifold forming part 224a and a cooling gas discharge gas manifold forming part 224b, and the fuel cell 10 is cooled by air-cooling. Between the cooling liquid flow passage forming part 226 and the cooling gas flow passage forming part 227, a separation sealing material 60 is arranged which is composed of permeable material that allows permeation of moisture only. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
