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)

Testing

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

Applications

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

Substrates

  • Graphite
  • Stainless steel
  • Membranes
  • Meshes
  • Fluoropolymers

Processes

  • S2S
  • R2R

Environment

  • In-vacuo/ In-situ
  • Ex-vacuo/ Ex-situ
