Embodiment Construction

[0026] The fuel cell local current density testing system of the present invention is mainly aimed at the local current testing system of a proton exchange membrane fuel cell, wherein an implementation example is roughly as follows Figure 5 As shown, the anode current collector plate 17 is included to lead out the reaction current and provide a flow channel for the reaction gas. In the example of a proton exchange membrane fuel cell, the anode gas is hydrogen. There are a plurality of independent metal small electrodes 19 on the large anode current collector plate, and an insulating material is used to seal 20 between the small electrodes and the large current collector plate, so that the small electrodes and between the small electrodes and the large anode current collector plate are absolutely insulated. Moreover, an anode flow field 16 is processed on the anode current collector plate composed of the small electrode and the large anode current collector plate to provide cir...

Abstract

This invention relates to a regional current test system for proton exchange membrane fuel batteries including an anode collecting board, a membrane electrode and a cathode collecting board, in which, an anode gas flow field is processed on the anode collecting board to provide a flow channel for the anode gas, collect current generated by the membrane electrode and bring out the current, besides, the membrane electrode provides reaction field for anode and cathode reaction gas, and the proton exchange membrane conducts proton and water to finish the reaction, cathode and anode provide reaction field for various gas and convey current to the collecting board. A reaction gas flow field is processed on the cathode collecting board to provide a flow channel for the cathode gas and collect current generated by the membrane electrode to carry it to outside current.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, in particular to a subregional current testing system for a proton exchange membrane fuel cell. Applied to the local current test of proton exchange membrane fuel cell (proton exchange membrane fuel cell). Background technique [0002] With the progress of human civilization, the consumption of traditional energy such as coal, oil and natural gas continues to rise, causing serious pollution of the earth, leading to the deterioration of the greenhouse effect and acid rain. Human beings have clearly realized and realized that the reserves of natural energy are limited, and if they are continuously abused, they may be exhausted in the near future. Therefore, various countries in the world are researching new alternative energy recently, and fuel cell (fuel cell) is one of the options that is always necessary and has development potential and practical value. Compared with traditional internal c...
