Product details
Julid can photochemical etching flow field bi-polar plates used in PEM (photon Exchange membrane), Fuel cells. Bi-polar plates, or separator plates, are conductive plates in a fuel cell stack that act as an anode for one cell and a cathode for adjacent cells.
The fuel cell plate contain flow channels for the fluid feeds and may contain conduits for heat transfer.
Julid can produce plates with interlacing front and back side channels to produce a corrugated effect for cooling purposes.
Tolerances up to 0.015mm. Material can be Titanium and stainless steel.
