Abstract:
One embodiment of the invention includes a method including applying a first ink comprising carbon over a substrate and drying the first ink to form a first electrode layer, applying a second ink including a second catalyst over the first electrode layer and drying the second ink to form a second electrode layer, and applying a third ink comprising an ionomer solution over the second electrode layer and drying the third ink to form an ionomer overcoat.
