In recent years, in addition to Honda, Toyota, Hyundai and other OEMs that have launched hydrogen fuel cell models that can be mass-produced, other internationally influential OEMs such as Daimler, Audi, BMW, etc. have also maintained their continued commitment to hydrogen fuel cell vehicles. Research and development, upstream international parts companies have also increased the development and layout of fuel cell vehicle related components. Recently, Schaeffler showcased its newly developed fuel cell technology at the 46th Tokyo Motor Show, as well as innovative technologies for the future sustainable energy chain and zero-emission transportation solutions.  



Fuel cells will play an important role in achieving sustainable transportation in the future. Among them, the bipolar plate is one of the important components of the fuel cell stack, its weight accounts for about 80% of the stack, and the cost accounts for about 24%. Currently, there are three types of bipolar plate materials for hydrogen fuel cells in the market: graphite, metal and composite materials. The metal bipolar plate developed by Schaeffler this time is formed by precise forming and coating of thin metal plates. Stacking this metal bipolar plate forms the core of the fuel cell system-the stack.

In the development of this technology, Schaeffler makes full use of the company’s traditional core technologies in material technology, molding technology and surface treatment on the one hand. On the other hand, it continues to expand to include electronic control systems, special air film bearings, and intelligent thermal Products such as management modules and passive hydrogen recirculation components.



Schaeffler Group Chief Technology Officer Uvi Wagner said: "In terms of solving global carbon emissions, it is not enough to rely on battery-powered vehicles. We also need new energy storage systems. Hydrogen fuel cell vehicles can solve the problem of mileage anxiety. Not only can it play a key role in the field of heavy trucks, but for passenger cars, a hybrid energy storage system that combines hydrogen and batteries is also an attractive solution."
