Abstract: SCREEN PRINTING FUEL CELL ELECTROLYTE MATRICES USING POLYETHYLENE OXIDE AS THE INKING VEHICLE A matrix for retaining the electrolyte in a fuel cell is applied to the surface of one or both of the electrodes by screen printing using an inking vehicle which is an aqueous solution of polyethylene oxide. This method produces a very thin, continuous and uniform matrix layer and is well suited to production operations.

Abstract: SCREEN PRINTING FUEL CELL ELECTROLYTE MATRICES A matrix for retaining the electrolyte in a fuel cell is applied to the surface of one or both of the electrodes by screen printing. In a preferred embodiment an aqueous solution of glycol is used as the inking vehicle to screen print a very thin, continuous and uniform matrix layer on the surface of an electrode.
