Latest Patents
One of Roethlein's latest patents is for an **Electrode substrate with integral edge seal and method of forming the**. This innovative process involves densifying the edges of a porous substrate plate used in fuel cell power plants. The approach includes impregnating a suspension of finely divided material into the interstitial spaces of the plate edges. Through a pressure differential applied between two press blocks, the suspension, in the form of an 'ink', is forced into the edges. After a catalyst layer has been applied, the ink penetrates to the inner surface, creating a filler band that is coplanar with the top surface of the catalyst layer. Once dried, these seals form a dense low porosity border on the substrate plates, ensuring the prevention of gas crossover and enhancing the efficiency of fuel cells.
