    摘要: The present invention provides a fuel cell comprising: a cathode catalyst layer 2; an anode catalyst layer 3; a proton conductive membrane 6 disposed between the cathode catalyst layer 2 and the anode catalyst layer 3; a liquid fuel tank 9 for storing a liquid fuel L; a fuel vaporizing layer 10 for supplying a vaporized component of the liquid fuel L to the anode catalyst layer 3; a surface layer 15 having an air intake port 14 for supplying an air to the cathode catalyst layer 2; and a moisture retention plate 13A, disposed between the surface layer 15 and the cathode catalyst layer 2, for preventing water generated at the cathode catalyst layer from being evaporated, wherein the moisture retention plate is composed of a laminated body comprising at least two kind of porous members 13a and 13b each having different moisture permeability (moisture retention property). According to the above structure, the water content generated at the cathode catalyst layer can be properly released as battery reaction is advances, and a part of the water content can be flown back to the anode catalyst layer side whereby cell output characteristics can be improved.
