<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of generating power stably for a long time while mounting a relatively high-concentration liquid fuel. <P>SOLUTION: The fuel cell has an anode electrode for oxidizing a liquid fuel, a cathode electrode for reducing oxygen, a solid polymer electrolyte film formed between the anode electrode and the cathode electrode, a power collection plate for taking out electrons following a generation reaction from the anode electrode, a first porous material for supplying the fuel to the anode electrode, and a second porous material for supplying fuel to the first porous material. The pore diameter of the first porous material is made smaller than that of the second porous material in a passive type fuel cell; where the solid polymer electrolyte film, the anode electrode, the power collection plate, the first porous material, and the second porous material are arranged in this order. <P>COPYRIGHT: (C)2007,JPO&INPIT |
