⚡ PEM Electrolyzer Bipolar Plates

Thin flat plate (0.3-2mm) with flow-field channels (parallel/serpentine/interdigitated), port holes for fluid distribution, large surface area up to 2m2

Design Principles

Material: Grade 1 (CP-Ti) is the base material for PEM electrolyzer bipolar plates due to its native oxide passivation at high anodic potential. Coated with Pt or Au to reduce contact resistance.

Form: Thin sheet (0.3-1mm) for flow-field plates. Precision stamping or etching of channel patterns. Coating (Pt/Au) applied via PVD or electroplating.

Engineering Trends

  • ▸ Process: Sheet stamping / chemical etching of flow fields
  • ▸ Process: Laser cutting of port holes
  • ▸ Process: PVD coating (Pt or Au)
