The present invention provides a separator for fuel cell, having a film on the surface, wherein the film has a water-holdability of 0.3 to 5.0 g per g of the film, or the film has a pore volume of 0.3 to 5.2 cc per g of the film; and, a process for producing a fuel cell separator by applying, onto a base material for fuel cell separator, a conductive coating containing at least a conductive powder and a binder, to form, on the base material, a film made of the conductive coating, wherein the proportions of the conductive powder and the binder are 100 parts by weight of the conductive powder and 1 to 1,000 parts by weight of the binder, or, a process for producing a fuel cell separator by applying, onto a base material for fuel cell separator, a conductive coating containing at least a conductive powder, a binder and a perishable additive, to form, on the base material, a film made of the conductive coating and then allowing the perishable additive to perish, wherein the proportions of the conductive powder, the binder and the perishable additive are 100 parts by weight of the conductive powder, 1 to 1,000 parts by weight of the binder and 0.1 to 100 parts by weight of the perishable additive. The fuel cell separator is superior in hydrophilicity and water-holding property. <IMAGE> |
