NOVELTY - A fuel cell consists of an electrolytic membrane (2), an anode catalyst layer (3), an anode gas-diffusion layer (4), a cathode catalyst layer (6), and a cathode gas-diffusion layer (7). The anode catalyst layer contains a fibrous supported catalyst which uses carbon fiber as support, and a granular supported catalyst which uses carbon particles as support. The ratio of fibrous supported catalyst in the anode catalyst at the surface (3a) facing the anode gas-diffusion layer is higher than that in the surface (3b) facing the electrolytic membrane.    USE - Fuel cell is used as power supply for mobile telephones and other small portable apparatuses.    ADVANTAGE - The fuel cell has excellent output characteristics.    DETAILED DESCRIPTION - A fuel cell consists of an electrolytic membrane, an anode catalyst layer laminated on one surface of the electrolytic membrane, an anode gas-diffusion layer laminated on the anode catalyst layer, a cathode catalyst layer laminated on the surface of electrolytic membrane opposite with respect to surface provided with anode catalyst layer, and a cathode gas-diffusion layer laminated on the cathode catalyst layer. The anode catalyst layer contains a fibrous supported catalyst which uses carbon fiber as support, and a granular supported catalyst which uses carbon particles as support. The ratio of fibrous supported catalyst in the anode catalyst at the surface facing the anode gas-diffusion layer is higher than that in the surface facing the electrolytic membrane. The weight ratio of fibrous supported catalyst at surface facing anode gas-diffusion layer is 60-90 wt.%, and the weight ratio at surface facing electrolytic membrane is 10-40 wt.%.
