Abstract

The invention relates to the technical field of fuel cells, in particular to a high-selectivity catalytic fuel cell and application thereof. The high-selectivity catalytic fuel cell comprises a cell body, an oxidation electrode, a reduction electrode, a proton exchange membrane arranged between the oxidation electrode and the reduction electrode and a circuit system. The proton exchange membrane separates the cell body into an oxidation chamber and a reduction chamber. The oxidation electrode is arranged in the oxidation chamber. The reduction electrode is arranged in the reduction chamber. The oxidation chamber is used for receiving an energetic agent and the oxidation electrode catalyzes the oxidation reaction of the energetic agent. The reduction chamber is used for receiving an oxidantand the reduction electrode catalyzes the reduction reaction of the oxidant. The electrons generated by the oxidation electrode are transferred to the reduction electrode via the circuit system. Theenergetic agent and the oxidant are pumped directly into the oxidation chamber and the reduction chamber respectively. The energetic agent is directly contacted with the oxidation electrode. The hydrogen ions generated by the energetic agent catalyzed by the oxidation electrode enter the reduction chamber directly through the proton exchange membrane so as to improve the catalytic efficiency.

Description

【Technical field】 [0001] The present invention relates to the technical field of fuel cells, in particular to a highly selective catalytic fuel cell and its application. 【Background technique】 [0002] Fuel cell is a kind of power generation device with high energy conversion rate and high reliability, which uses fuel and oxygen to react to generate water and convert chemical energy into electrical energy. The fuel cell is composed of a membrane that can conduct protons, 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 operation of the fuel cell, the fuel, especially the hydrogen H 2 Or the hydrogen-containing gas mixture is directed to the anode, where H is carried out at the anode 2 to H + electrochemical oxidation to release electrons. Proton H through electrolytes or proton-conducting membranes + Transport from the anode compartment to the cathode compartment...
