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. The movement of the valve body will be controlled to block or leak different oil drain holes. The oil inlet hole is normally open, and the hydraulic oil will enter different oil drain pipes, and then the valve body will be opened Through the oil pressure to push the oil rigid piston, the piston drives the piston rod, the piston rod drives the mechanical device. In this way, the mechanical movement is controlled by controlling the current of the electromagnet. The above is the working principle of the solenoid valve.
Although fuel cell vehicles are developing rapidly, from the perspective of commercialization requirements, there is still a certain gap in China's vehicle fuel cell technology. In the future, it is necessary to strengthen the layout of the following aspects of the Wholesale PEM fuel cell stack:
china fuel cell stack is not the actual battery stacked together, but a fuel cell term, which refers to a battery stack composed of multiple fuel cells in order to obtain a practical voltage. china fuel cell stack The key is the material and manufacturing technology that make up the battery stack. China fuel cell stack materials must have sufficient chemical stability and thermal stability. The electrochemical performance must meet the requirements, and all technical conditions must also be consistent in order to obtain good benefits. Size and weight should be minimized.
