Abstract
An electrochemical cell electrode, having clearly segregated and structured hydrophobic gas channels and electrolyte-filled catalyst channels is provided in which the size and shape of the various passages are such that they offer little resistance to the passage of reactants and products. The electrode consists of alternate layers of porous hydrophobic material and porous hydrophilic catalyst-containing material. The electrode is formed by first depositing the alternate layers of materials and then cutting the structure in a plane at right angles to the plane of deposition at a thickness equal to that of the end product. Electrodes of varying size can be constructed of panels so produced.
