Abstract

The invention relates to the technical field of fuel cells, in particular to a proton exchange membrane fuel cell metal bipolar plate beneficial to fluid distribution. The proton exchange membrane fuel cell metal bipolar plate comprises a substrate, a cathode plate, an anode plate and a proton exchange membrane, a plurality of anode grooves and cathode grooves are respectively formed in the two opposite sides of the substrate which are away from each other, and the directions of the anode grooves and the cathode grooves are consistent. The adjacent anode grooves and cathode grooves are distributed at intervals, the anode plate is fixedly embedded in cathode grooves, and and the cathode plate i fixedly embedded in cathode grooves. The substrate is also provided with proton exchange holes consistent with the anode grooves in direction, and the proton exchange membranes are fixedly embedded in the proton exchange holes. According to the invention, a flow field for optimizing the metal bipolar plate is realized, the risk of local under-inflation is reduced, and a fuel cell stack can be kept in normal operation.

Description

Technical field [0001] The present application relates to the technical field of fuel cells, and more particularly to a proton exchange membrane fuel cell metal bipolar panel that is conducive to fluid dispensing. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of the fuel into electrical energy, also known as electrochemical generators. It is a fourth power generation technology after hydraulic power generation, thermal power generation and atomic power generation. Since the fuel cell is converted to electric energy through an electrochemical reaction to convert the Gibbs free energy portion of the fuel into electrical energy, it is not limited by the Carno cycle effect, therefore high efficiency; additional, fuel cell fuel and oxygen as raw materials, Without mechanical transmission components, there is no noise pollution, and the exhaustible gas is extremely small. From the perspective of saving energy and protecting an...
