Abstract
A composite graphite-resin porous electrode structure is made by intimately mixing powdered graphite with the resin monomers and partially polymerizing and grinding the mixture before forming a moulding composition by adding a pore-forming agent removable by decomposition or leaching to form uniformly-sized pores. A catalyst for the electrode reaction is incorporated in the electrode with the pore-forming agent or in a thin layer during moulding and an electrically-conductive strengthening element which acts as a rheophore is also incorporated during moulding. Layers having different pore sizes may be formed and a water-repellent film is applied to one face of the electrode.
