Abstract
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.
