Abstract

The invention relates to the technical field of fuel cells, and in particular to a highly selective catalytic fuel cell based on mixed liquid and application thereof. The highly selective catalytic fuel cell based on mixed liquid includes a battery body, an oxidation electrode, a reduction electrode and a circuit system, the battery body is formed with a reaction chamber used for receiving a fuelsolution, and the oxidation electrode and the reduction electrode are arranged in the reaction chamber, the oxidation electrode catalyzes the fuel solution to generate the oxidation reaction, the reduction electrode catalyzes the oxidation reaction of the fuel solution, and the electrons generated by the oxidation electrode are transmitted to the reduction electrode through the circuit system. Inthe invention, a proton exchange membrane is not required for isolation of the reaction chamber so as to simplify the battery structure, reduce the battery weight and improve the catalytic efficiency.

Description

【Technical field】 [0001] The invention relates to the technical field of fuel cells, in particular to a mixed liquid-based high-selectivity catalytic fuel cell and its application. 【Background technique】 [0002] A fuel cell uses fuel and oxygen to react to generate water and convert chemical energy into electrical energy. It is a power generation device with high energy conversion rate and strong reliability. The fuel cell consists of a proton-conducting membrane, electrodes arranged on both sides of the membrane, and gas diffusion layers distributed on the back of the membrane-electrode units on both sides. During the working process of fuel cells, fuel, especially hydrogen H 2 Or the mixed gas containing hydrogen is directed to the anode, where H 2 to H + Electrochemical oxidation to release electrons. Proton H through an electrolyte or a proton-conducting membrane + Transport from the anode compartment to the cathode compartment. Electrons produced at the anode are...
