Abstract
A conductive resin molding for use in the separator of a fuel cell and its producing method in which lowering of production yield and increase of machining cost, which are the most important problems with the spread of fuel cell, can be suppressed. The conductive resin molding is characterized by containing 1-9 vol % of high boiling point oil against the entire resin composition. Alternatively, high density expanded graphite prepared to have a specific gravity of 1.8 or above is employed as a conductive compounding agent. Alternatively, the conductive resin molding can be molded by flash flow compression molding.
