PURPOSE:To obtain an acid electrolyte type liquid fuel cell with a high performance by using a multi-element catalyst of platinum-ruthenium or platinum-tin as a base and added with an auxiliary component for a fuel electrode of the acid eletrolyte type liquid fuel cell using methanol, formaldehyde, or formic acid as the fuel. CONSTITUTION:A fuel electrode 4 is composed of an electrode substrate and catalyst, and is opposite to an air electrode 6 separated by an electrolyte chamber 5, where a positive ion exchange film may be sometimes provided. The air electrode 6 is composed of an electrode substrate, catalyst, and water-proof film, and one side faces the air chamber 9. An air inlet 7 and air outlet 8 are provided on an air chamber 9 to feed and discharge the air. One to eight weight units of a polymeric compound binding agent such as polytetrafluoroethylene, polyethylene, or polyvinyl chloride is added to 30wt. units of catalyst powders, and they are kneaded into catalyst powders, which are coated at 30mg/cm<2> on a metal net made of gold, platinum, niobium, or tantalum in 20-80 meshes to obtain an electrode. |
