World leaders in chemical etching

Metal fuel cell plates

Photofab can chemically etch bi-polar plates used in Proton Exchange Membrane (PEM) fuel cells.

Fuel cell development has moved forward a long way in the past few years, Photofab work with some of the industries key minds on trialing new designs for separator plates (conductive plates within a fuel cell stack acting as an anode for one fuel cell and a cathode for adjacent cells).

Metal Fuel Cell Plate benefits

  • Improved electrical and thermal conductivity over non-metal solutions
  • When compared with Graphite, more resistent to mechanical impact
  • Ability to vary thickness of plates, optimising space
  • Low tooling costs
  • Fast delivery
Metal fuel cell plates

A product often associated with Metal Fuel Cell Plates is Heat Exchangers. These are finely etch either meshes or channelled plates which rely on precision accuracy and innovative design. Photofab have again worked with a number of organisations on the development of heat exchangers and would welcome the opportunity to also work with your selves.
