Fuel cell system have several benefits over conventional Carbonic acid battery and lithium battery technologies currently used in many traditional electric bicycle .Fuel cell system can operate at higher efficiencies than Carbonic acid battery and lithium battery and can convert the chemical energy in the fuel directly to electrical energy with efficiencies capable of exceeding 60%. Fuel cell system have lower or zero emissions compared to Carbonic acid battery and lithium battery. Hydrogen fuel cell system emit only water, addressing critical climate challenges as there are no carbon dioxide emissions. Fuel cell system are quiet during operation as they have few moving parts. One of the main components of hydrogen fuel cell is graphite Bipolar plate. In 2015,VET entered the fuel cell industry with its advantages of producing graphite Bipolar plates.Founded company Miami Advanced Material Technology Co., LTD. After years of research and development, vet have mature technology for producing air cooling 10w-6000w Hydrogen fuel cells,UAV hydrogen fuel cell 1000w-3000w, 150W to 1000W Hydrogen Fuel Cell system for Electric Bike, the hydrogen reactor system below 1kW can be well matched on electric bicycles or motorcycles, with stable performance and high cost performance price which has been highly praised by domestic customers
