Study battery microstructure

The scanning electron microscope (SEM) was used to study the microstructure of the battery. The device tests the overall electrical performance of the battery, and the analysis believes that the main reason is that the anode substrate and the electrolyte have co-shrinkage matching during co-firing. Experiments show that

Proton exchange membrane fuel cell system; portable power supply; system thermal management Proton exchange membrane fuel cell system is a high-efficiency, environmentally friendly power generation system. In recent years, with the development of high-power proton exchange membrane fuel cell systems used in electric vehicles, ships and local power stations, small-power (below) portable proton exchange membrane fuel cell systems have also made great progress. Digital products such as computers, as well as portable mobile power supplies, emergency backup power supplies, and military communications power supplies have broad application prospects. At present, the research and development of low-power proton exchange membrane fuel cell system has attracted more and more countries and enterprises' attention, and it has become a new research hotspot in the field of proton exchange membrane fuel cell. We have designed, developed, and developed a miniaturized, portable, and high-efficiency proton exchange membrane fuel cell system, and conducted a series of performance tests on the developed portable proton exchange membrane fuel cell system demonstration prototype and found that it affects the performance of the portable system. Key issues and proposed solutions.

The working principle of proton exchange membrane fuel cell Proton exchange membrane fuel cell is a power generation device that directly converts chemical energy stored in fuel (such as hydrogen) and oxidant (such as oxygen and air) into electrical energy. The main features of this device It is efficient and environmentally friendly.
