The present disclosure provides a simple and inexpensive method of making a flow field plate that exhibits increased durability under conditions of use comprising the steps of: a) providing a flow field plate comprising at least one flow field surface; b) applying a dry carbon powder to at least one flow field surface of the flow field plate; and c) buffing the carbon powder onto the flow field surface. In another aspect, the present disclosure provides a method of making a coated flow field plate comprising the steps of: a) providing a flow field plate comprising at least one flow field surface; b) rubbing at least one flow field surface of the flow field plate with a dry carbon solid; and optionally c) buffing the carbon onto the flow field surface.
