Abstract: A method of producing a separator plate for a low temperature fuel cell. In the method, a sheet article made of aluminum or aluminum alloy is coated with a layer of an electrically-conductive heat-activated polymerizable material, preferably dissolved or suspended in a volatile liquid. The article is preferably heated to a temperature below the full-cure temperature to drive off the volatile liquid to create a dried layer of polymerizable material. The surface is then coated with a catalyst to produce a catalyst-coated layer of polymerizable material. The article is then heated to the full-cure temperature to fully polymerize the polymerizable material and to attach the catalyst. The invention also relate to a separator plate having a structure indicated above.
