Screen printing process for catalyst layers.

  • Conceptual design of membrane electrode assemblies (MEA)
  • Evaluation of machines, components, and materials (raw materials, pastes and inks, membranes)
  • Paste and ink development inclusive homogenization and characterization
  • Development of processes and methods for quality control along the complete MEA value chain
  • Ex-situ and in-situ characterization of layers and cell components
  • Techno-economic analysis of production processes
Voltage dependent on ionomer content

Voltage at a current denisty of 3 A/cm2 in dependence of ionomer content and platinum loading within a screen-printed catalyst layer. Specific paste formulations – as delveloped at Fraunhofer ISE – enable a reduction in platinum loading down to 0.2 mg/cm2 at constant output power of the fuel cell.
