The “Blood Vessels” Of Hydrogen Fuel Cells – Silicone Hoses

“Hydrogen fuel cells represent the pinnacle of future energy, and hydrogen energy silicone hoses provide a solid support for them, ensuring not only a stable supply of hydrogen, but also durability and reliability, allowing the fuel cell system always to operate efficiently”

Hydrogen fuel cells are an environmentally friendly and efficient energy solution.

The working principle of a hydrogen fuel cell vehicle is: hydrogen gas is sent to the anode plate (negative electrode) of the fuel cell. Through the action of the catalyst (platinum), an electron in the hydrogen atom is separated, and the hydrogen ions (protons) that have lost the electron pass through The proton exchange membrane reaches the cathode plate (positive electrode) of the fuel cell, but electrons cannot pass through the proton exchange membrane. The electrons can only reach the cathode plate of the fuel cell through the external circuit, thereby generating current in the external circuit. After the electrons reach the cathode plate, they recombine with oxygen atoms and hydrogen ions to form water. Since the oxygen supplied to the cathode plate can be obtained from the air, as long as hydrogen is continuously supplied to the anode plate, air is supplied to the cathode plate, and water (steam) is taken away in time, electric energy can be continuously provided. The electricity generated by the fuel cell supplies power to the motor through inverters, controllers and other devices, and then drives the wheels to rotate through the transmission system, drive axle, etc., allowing the vehicle to drive on the road. Compared with traditional vehicles, the energy conversion efficiency of fuel cell vehicles is as high as 60 to 80%, which is 2 to 3 times that of internal combustion engines. The fuel of the fuel cell is hydrogen and oxygen, and the product is clean water. It does not produce carbon monoxide and carbon dioxide, and does not emit sulfur or particulates. Therefore, hydrogen fuel cell vehicles are truly zero-emission, zero-pollution vehicles, and hydrogen fuel is the perfect automotive energy source!

In order to ensure the stable operation of the fuel cell system, we have launched a high-performance silicone hose line specially used for this system. Our hoses are commonly used in fuel cell air supply systems, hydrogen supply systems, and water and heat management systems
