Customer ServiceThe highly integrated metallic bipolar plate reduces the total cost for fuel cell stack by up to 10 %. The two reasons are the integration of the sealing system and the design of the conductive functional coating. The stamped bead seals are an integral part of the plate and contrary to inlay seals, do not require any further assembly processes.

Standardized test sequence for qualifying bipolar plates and fuel cell components (© Dana) The highly integrated metallic bipolar plate reduces the total cost for fuel cell stack by up to 10 %. The two reasons are the integration of the sealing system and the design of the conductive functional coating.
Soon, the new technology will touch the whole hydrogen fuel cell industry and reduce the cost with mass production capacity of one million pieces per year. The price of metal bipolar plates accounts for about 10%-15% of the current cost of mainstream high-power fuel cell engines.
Fuel cell technology has the potential to change mobility in the long term. So far, however, this form of powertrain has not been able to gain widespread acceptance, not least because of the high cost of fuel cell stacks. The metallic bipolar plate from Dana is intended to change this and drive forward the commercialization of the fuel cell.
The bipolar plate largely determines the power density, weight, and cost of a fuel cell stack. The basic layout of the metallic bipolar plate therefore decides the efficiency of the fuel cell system.
