<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of generating power efficiently by increasing oxygen concentration in the air supplied to an air electrode. <P>SOLUTION: In a fuel cell of a structure in which a solid electrolyte film layer, a fuel electrode installed at its one side, and a fuel gas passage contacted with it, an air electrode installed at the other side and an air passage contacted with it are installed, and in which a gas fuel (hydrogen or the like) and a liquid fuel (ethanol, dimethyl ether or the like) are fuel sources, an oxygen selective transmissive separating film is installed at the air electrode, or a conductive oxygen selective transmissive separating film is used or a dense carbon film is used. <P>COPYRIGHT: (C)2007,JPO&INPIT |
