The operational mannered null hydrion conductivity high-molecular electrolyte membrane

摘要

PROBLEM TO BE SOLVED: To provide a conductive separator plate for a high molecular electrolyte type fuel cell using a metal easy to be worked as a raw material, capable of maintaining the chemical inert characteristic even if a surface exposed to the gas is exposed to the acid atmosphere to restrict corrosion and dissolve and having excellent conductivity. SOLUTION: This conductive separator plate is formed of a stainless steel plate having an uneven surface, and the surface is coated with a passive state film enriched with Cr.
