Fuel cell separator production method, fuel cell separators, and polymer electrolyte fuel cells

摘要

Fuel cell separators which are highly hydrophilic and undergo little leaching of substances that inhibit power generation can be produced by shaping a composition made primarily of an electrically conductive powder and a binder to form a shaped body, coating and impregnating the shaped body with a metal oxide-containing hydrophilic resin, then curing the hydrophilic resin.
