Current situation and development of fuel cell vehicle industry chain in China
It is urgent to develop hydrogen energy and fuel cell industry in China. In the past 19 years, China's dependence on foreign oil and natural gas was 70.8% and 43% respectively. In recent years, the self-sufficiency rate of crude oil and natural gas has decreased year by year, and China's energy security has a certain potential threat.
How hot is hydrogen energy 3 trillion investment on the road!
In just five months, the cumulative global investment in hydrogen energy jumped from US $300 billion to US $500 billion !
Safety components of hydrogen supply system
The protection measures of hydrogen system mainly include safety design of high-pressure hydrogen storage bottle and hydrogen pipeline, and installation of various safety facilities.
Thermal management scheme of hydrogen fuel cell
Proton exchange membrane fuel cell (PEMFC) has many advantages, such as high efficiency, clean, zero emission and so on. In practical application, 40% ~ 60% of the chemical energy of PEMFC fuel is converted into electrical energy, and most of the remaining energy is converted into heat energy.

How to choose a pem electrolyzer manufacturer
When we use electrolyzed water to produce hydrogen, we must have a lot of knowledge points that need to be understood, and when purchasing pem electrolyzers, we can also choose different brands from the aspects of product quality, market price, consumer recognition, etc., In order to allow everyone to buy high-quality products, let's talk about how to choose a pem electrolyzer manufacturer?
About hydrogen pressure reducing valve
Hydrogen pressure reducing valve is to control the opening of the opening and closing parts in the valve body to adjust the flow of the medium, reduce the pressure of the medium, and adjust the opening of the opening and closing parts with the help of the pressure behind the valve, so as to keep the pressure behind the valve within a certain range.
Do you know how solenoid valve works?
There is a closed cavity in the solenoid valve. There are through holes in different positions. Each hole leads to different oil pipes. There is a valve in the middle of the cavity and two electromagnets on both sides. The valve body will be attracted to which side when the magnet coil is electrified.
