sealing valve

The air compressor in the fuel cell air intake and exhaust system is responsible for pressurizing the air and coordinating with the fuel cell sealing valve according to the needs of the fuel cell stack. Work to ensure that the air flow and pressure in and out of the fuel cell stack are within the appropriate range.fuel cell sealing valve adopts butterfly valve form. According to the application scope of the product, its function can be divided into stop valve,Back pressure valve,Bypass Valves, etc.

After the fuel cell is shut down, the shut-off valve and back pressure valve in the fuel cell system need to meet the sealing capacity. In order to achieve the cathode circuit in the shutdown state, the cathode circuit can be sealed to prevent air from entering the battery stack and affecting the life of the battery stack .
