Metallic bipolar plates
PEMFC bipolar plates made of metal offer clear advantages in terms of cost efficiency, power density, and cold-start capability of fuel cells. Using high-precision progressive tooling, EKPO produces metal bipolar plates in a fully automated, interlinked manufacturing process.
PEMFC stacks consist of alternating stacks of membrane electrode assemblies (MEAs) and bipolar plates. They are interspersed with porous layers that serve to distribute the gas and transfer the electric current. The bipolar plate separates the media and distributes them within the stack. It also ensures uniform cooling of the stack and transfers the electric current to the adjacent cells.
Good to know: Metal bipolar plates from EKPO Fuel Cell Technologies also excel in electrolysers with their high power density and cost-efficiency. Find out more
