STAINLESS STEEL SEPARATOR FOR FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a stainless steel separator for a fuel cell providing compatibility between low contact resistances and high corrosion resistances.

SOLUTION: In the separator for the fuel cell, a steel plate surface facing a fuel electrode 3 is pickled and a steel plate surface facing an oxide electrode 2 is subjected to surface roughening such as electrolytic etching. The surface roughening can be applied before or after pickling and passivation processes. Or the roughened steel plate surface can be used in an oxide electrode 2 side without applying the pickling and passivation processes.
