Innovative cooling systems for fuel cells

In mobility, there is a rethinking of resource-saving and emission-free drives. In addition to battery-powered vehicles, fuel cells for the electro mobility are the focus. The goal is to reduce the manufacturing costs by large-scale technical use of metallic bipolar plates, because this can be the total mass of the fuel cell stacks and resulting production costs can be reduced. The reduction in space leads to an increase in power density, which new concepts for dissipating the heat loss are required. Reliable functional operation of the cooling system must be ensured even with changing temperature influences, accelerations or shocks. Accordingly, the seal, which prevents the leakage of liquids and gases and provides electrical insulation between the bipolar plates and their exploration are major focuses in the project (sealing concept and processing technologies).


  •  Reduce the manufacturing costs of fuel cell drives
  • Mass production of metallic bipolar plates
  • Increasing the power density of fuel cell stacks



  • Research on an innovative cooling system based on two-phase cooling
  • Transferability of the manufacturing processes for high-volume production of bipolarplates on the two-phase cooling
  • Considerations for sealing the fuel cell stack
  • experimental proof of function under realistic conditions
