Method for manufacturing fuel cell separators, comprises placing mask on material to be treated, injecting electrolyte perpendicularly on to material face through an electrode and removing mask

摘要

An electrolytic solution (11) is pumped (P) and filtered (F) and directed to electrodes (30) through channels (16,17). The material for treatment (B) is fixed to a sliding support (22) and masked (M). The electrolyte passes through the electrodes, meets the workpiece perpendicularly and is returned (13) to the electrolytic reservoir. An electricity supply (26) maintains the electrodes at a potential relative to the workpiece Independent claims are made for equipment adapted to the method.
