Hydrogen fuel cell stack testing device with uniformly stacked cell units

Abstract

The invention relates to the technical field of hydrogen fuel cell testing, in particular to a hydrogen fuel cell stack testing device with uniformly stacked cell units, which comprises a bottom plate and a conveyor belt, a groove is formed in the bottom plate, the conveyor belt is rotatably mounted on the inner side wall of the groove, a first L-shaped plate is arranged on one side of the bottom plate, and a second L-shaped plate is arranged on the other side of the bottom plate. A telescopic air cylinder is fixedly installed at the top of one end of the first L-shaped plate, a transverse plate is arranged at the top of the bottom plate, a cathode connecting end and an anode connecting end are fixedly installed at the bottom of the transverse plate from left to right in sequence, a shell is fixed to one end of the first L-shaped plate, and a detection meter is fixedly installed on the inner side wall of the shell; the cathode connecting end and the anode connecting end are respectively connected with the detection meter through electric wires, and a stamping mechanism is arranged at the top of the bottom plate. The test efficiency is high, the labor intensity of a user is reduced, and unqualified products can be conveniently marked so as to facilitate later maintenance.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cell testing, in particular to a hydrogen fuel cell stack testing device with evenly stacked battery cells. Background technique [0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of electrolyzing water. Hydrogen and oxygen are supplied to the anode and cathode respectively. After the hydrogen diffuses outward through the anode and reacts with the electrolyte, Electrons are released to reach the cathode through an external load. Dry batteries and batteries are energy storage devices that store electrical energy and release it when needed; strictly speaking, hydrogen fuel cells are a power generation device, like a power plant. An electrochemical power generation device that directly converts chemical energy into electrical energy. In addition, the el...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a hydrogen fuel cell stack testing device with evenly stacked battery cells to solve the problem that the existing testing method proposed in the above-mentioned background technology is generally a hand-held testing meter, and the testing head is placed on the cathode and anode of the battery. On the other hand, observe the test results through the test table. This test method has the problems of low test efficiency and high labor intensity, and it is inconvenient to mark the unqualified products and inconvenient for later maintenance.
