Abstract

An organic fuel battery comprises a membrane electrode and a battery casing, wherein the membrane electrode is arranged in the battery casing, the membrane electrode comprises an anode, a cathode, and an atom exchange membrane between the anode and the cathode. The battery further comprises at least one thermal conductive element partly in the battery casing while another portion is extruded outside the battery casing. Compared with prior art, the power density of battery is improved more than one times. Via the thermal contact with a heater of electric device, the invention can effectively utilize the waste heat of electric device, and effectively improve the power density of battery with resolved thermal pollution problem.

Description

technical field [0001] The present invention relates to a fuel cell, in particular to an organic fuel cell. Background technique [0002] A fuel cell is a device that converts chemical energy into electrical energy. Existing fuel cells generally include a membrane electrode, which includes an anode, a cathode, and a proton exchange membrane between the anode and the cathode. [0003] The anode is a gas diffusion electrode, and its supporting material is generally composed of conductive carbon fiber or carbon cloth. Between the anode and the proton exchange membrane is a catalyst that catalyzes the anode reaction. The anode catalyst is generally platinum powder, platinum-containing alloy powder, platinum supported on a carrier, or platinum-containing alloy powder supported on a carrier. The platinum-containing alloy contains platinum and one or more selected from ruthenium, tin, iridium, osmium and rhenium. The carrier is a conductive carrier with a high specific surface,...
