The function of
bipolar plate (also known as diaphragm) is to provide gas flow channel, prevent the collusion between hydrogen and oxygen in the battery gas chamber, and establish a current path between the Yin and Yang poles in series. On the premise of maintaining a certain mechanical strength and good gas resistance, the thickness of bipolar plate should be as thin as possible to reduce the conduction resistance to current and heat
Carbonaceous materials. Carbonaceous materials include graphite, molded carbon materials and expanded (flexible) graphite. The traditional bipolar plate adopts dense graphite and is machined into gas channel· The graphite bipolar plate has stable chemical properties and low contact resistance with mea.
Bipolar plates need proper surface treatment. After nickel plating on the anode side of the bipolar plate, the conductivity is good, and it is not easy to be wetted by the electrolyte, which can avoid the loss of electrolyte. The flexible contact between the electrolyte diaphragm and the bipolar plate outside the effective area of the electrode can effectively prevent the gas from leaking out, which is the so-called “wet seal”. In order to reduce the corrosion of molten carbonate on stainless steel at the “wet seal” position, the bipolar plate frame needs to be “aluminized” for protection
One of the main components of hydrogen fuel cell is graphite fuel electrode plates. In 2015,VET entered the fuel cell industry with its advantages of producing graphite fuel electrode plates.Founded company Miami Advanced Material Technology Co., LTD.
After years of research and development, vet have mature technology for producing 10w-6000w Hydrogen fuel cells. Over 10000w fuel cells powered by vehicle are being developed to contribute to the cause of energy conservation and environmental protection.As for the biggest energy storage problem of new energy, we put forward the idea that PEM converts electric energy into hydrogen for storage and hydrogen fuel cell generates electricity with hydrogen. It can be connected with photovoltaic power generation and hydropower generation.
