<P>PROBLEM TO BE SOLVED: To provide a fuel cell in which stay of water generated by an electrochemical reaction is controlled. <P>SOLUTION: The fuel cell is equipped with a battery thin film assembly 30, a composite electrode plate 40, and a current collector plate 50, and the composite electrode plate and the current collector plate are installed respectively at the both outside faces of the battery thin film assembly. The composite electrode plate has a non-porous material plate 41 and a porous material plate 42, and the non-porous material plate has a recessed groove 413 formed on a bottom plate by the bottom plate and a frame, and has a passage 414 formed on the bottom face. The porous material plate is installed in the recessed groove interposed between the battery thin film assembly and the bottom plate. Drift velocity of the fuel is improved by the gap on the porous material plate and water produced after the electrochemical reaction is made to flow out rapidly from the fuel cell by the passage, and power generation performance of the fuel cell is improved. <P>COPYRIGHT: (C)2011,JPO&INPIT |
