CA 2436901

A fuel cell separator is manufactured by charging a porous molding material into a mold, compression molding the porous material to create a porous molded body, then impregnating predetermined regions of the porous molded body with a binder to form dense areas. The process lends itself well to the low-cost, high-volume production of fuel cell separators having a dense structure, which separators, even when bearing a complex channel geometry, can readily be imparted with a uniform density and uniform pores and moreover exhibit a high planar and dimensional precision.
