Description

Technical Field

[0001] The utility model relates to the technical field of fuel cell testing, and particularly relates to a fuel cell system test cabinet with a layered frame structure. Background Art

[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 respectively supplied to the anode and the cathode. After hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released and reach the cathode through an external load. During the testing process of a hydrogen fuel cell system, it is necessary to fix the hydrogen fuel cell on a test platform in a laboratory. The existing test cabinet platforms for hydrogen fuel cell systems cannot meet the testing requirements of hydrogen fuel cell systems of different sizes. Therefore, it is necessary to configure multiple types of test platforms according to the testing work of hydrogen fuel cell systems of different models. Moreover, frequently changing the test site layout is very likely to cause the test equipment to be arranged in a mess, making it difficult to make timely planning arrangements and reasonable adjustments, often resulting in chaotic management of the test site and greater potential safety hazards. More importantly, the development cost increases and the R & D progress is affected. The test cabinet for hydrogen fuel cell systems is of great significance for the development evaluation, performance assessment, and parameter verification of fuel cell systems, and is an indispensable basic equipment in the R & D process of fuel cells. Therefore, this application proposes a fuel cell system test cabinet with a layered frame structure. Summary of the Invention
