Production of gas separators for use in fuel cells and equipment used therefor |
摘要 |
To provide a method capable of producing a separator integrated with a gas flow channel of fuel cells efficiently at low costs without deteriorating processing accuracy and the like. A plane-facing electrode nozzle 30 is placed oppositely to the face to be processed, which is partially covered with a mask M, of base material B of a separator. Under the condition of feeding electricity to the electrode nozzle 30 and the base material B of a separator, an electrolytic solution is injected and fed from the side of the electrode nozzle 30 to the face to be processed of the base material B from a direction that is almost perpendicular to the face. Thereby, the unmasked portion undergoes electrolytic etching with the electrolytic solution lying between the face to be processed and the electrode nozzle 30 to form recessed portions for making a gas flow channel.
