Elcon - Photochemically Etched Bipolar Plates
Elcon provides high strength and durable photochemically etched fuel cell plates that can withstand extreme environments in your applications. Photo etching offers fuel cell and electrolyzer plate engineers many advantages to combat their design, time, and cost challenges. The geometric complexity and tolerances offered by photochemical etching not only make it a desirable manufacturing process but, in some instances, the only technology suitable for critical components.
