The "hydrogen" wind came, and the times were surging. As a clean energy that supports the sustainable development of human beings, the proportion of hydrogen energy in the global energy structure has increased year by year, and the research of hydrogen fuel cell technology is in the ascendant. Science has no national borders, and scientific research equipment has a good country. With the comprehensive competition in the field of hydrogen energy technology in the United States and China, in order to avoid the risk of "stuck neck", more and more universities and scientific research units laboratory choose DC 980 and other domestic hydrogen fuel cell test systems for scientific research activities to enhance China's hydrogen energy Technical competitiveness.

At present, hydrogen fuel cell research focuses on the field of proton exchange membrane fuel cells (PEMFC), conducting multi parameter polarization curve testing, battery performance evaluation, durability control strategy research, etc. through fuel cell testing systems, researching feasible solutions, improving battery efficiency and performance, which is of great significance for the application of hydrogen fuel cell technology.

The hydrogen fuel cell itself is a power generation device. In order to grasp the performance data of the fuel cell, it is necessary to simulate a load to test a single cell. However, the testing requirements for a single cell fuel cell are strict. A single cell can only generate a voltage of no more than 1V, and the electronic load has internal resistance. The larger the load current, the higher the corresponding minimum load voltage. If we require electronic loads to start testing from 0V, we will face the problem of high current load caused by "0V start". This poses challenges to the safety, reliability, and stability of fuel cell testing equipment.

If there is a need for pain, there is a solution. The DC series PEM fuel cell testing system developed by Wuhan DC New Energy has the function of "0V start, full current load". It can not only simulate various characteristics of fuel cells, but also detect parameters such as voltage, current, power, and efficiency during testing. Experimental personnel can confidently conduct a "0V start, full current load" test. The R&D engineer of the DC preset multiple protection mechanisms such as "unloading the load, stopping heating, nitrogen cleaning, and stopping fuel supply". There is also a one key manual emergency stop switch, fully ensuring the safety of scientific researchers during experimental operations.

Currently, the commercialization scale of hydrogen fuel cells is constantly expanding, and there is a surge in demand for related testing equipment. Academician Yi Baolian, a Chinese fuel cell expert, pointed out that "establishing a testing and durability evaluation system for key components, fuel stacks, and battery systems. Strengthening the research and development, testing, and verification application of core materials and key components of fuel cells, only by continuously achieving technological progress and improving technological level, can fuel cell vehicles compete with pure electric vehicles on the same platform." As a professional manufacturer of fuel cell testing systems in China, Wuhan DC New Energy continuously innovates and develops more precise and user-friendly domestic fuel cell testing equipment to support the development of China's hydrogen energy industry.
