Fuel cells

Automotive, stationary and industrial applications require highly efficient energy conversion solutions. Fuel cell manufacturers have to ensure excellent quality while addressing high troughput specifications and finally maximizing the uptime of the equipment. Coating processes have to monitored, especially for:

  • Bipolar plates (BPP)
  • Gas diffusion electrode (GDE)
  • Gas diffusion layer (GDL)
  • Membrane electrode assembly (MEA)


  • Sheet resistance
  • Conductivity
  • Functionlization
  • Thickness
  • Homogeneity
  • Area weight
  • Drying status


  • Deposition process control
  • Tempering process control
  • Drying status control
  • Quality control


  • Graphite
  • Stainless steel
  • Membranes
  • Meshes
  • Fluoropolymers


  • S2S
  • R2R


  • In-vacuo/ In-situ
  • Ex-vacuo/ Ex-situ
  • Wet and dry
  • Inline
  • Offline


  • Inks
  • Pastes
  • Amorphous Carbon
  • Catalysts
    • Pt


  • Alkaline fuel cells (AFC)
  • Polymer electrolyte membrane fuel cell (PEM)
  • Direct methanol fuel cell (DMFC)
  • Phosphoric acid fuel cell (PAFC)
  • Molten carbonate fuel cells (MCFC)
  • Solid oxide fuel cells (SOFC)
