Abstract

The present application relates to the technical field of fuel cells, and in particular to a proton exchange membrane fuel cell metal bipolar plate that facilitates fluid distribution, which includes a substrate, a cathode plate, an anode plate and a proton exchange membrane. There are multiple anode cells and cathode cells. The direction of anode cells and cathode cells is the same. The adjacent anode cells and cathode cells are distributed at intervals. There is also a proton exchange hole that is in line with the direction of the anode tank, and the proton exchange membrane is fixedly embedded in the proton exchange hole. The present application can optimize the flow field of the metal bipolar plate, reduce the risk of partial gas shortage, and keep the fuel cell stack normal. running effect.

Description

technical field [0001] The present application relates to the technical field of fuel cells, and in particular, to metal bipolar plates for proton exchange membrane fuel cells that facilitate fluid distribution. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Because the fuel cell converts the Gibbs free energy of the chemical energy of the fuel into electrical energy through electrochemical reaction, it is not limited by the Carnot cycle effect, so the efficiency is high; in addition, the fuel cell uses fuel and oxygen as raw materials, and at the same time There are no mechanical transmission parts, so there is no noise pollution and very few harmful gases are emitted. From the perspective of saving energy and protecting the ecological environmen...
