Electrocatalyst and hydrophobic polymer particles are combined to form an aqueous suspension which is then applied to a conductive substrate to form an electrode. The colloidal chemistry of the suspension of electrocatalyst particles and hydrophobic polymer particles is controlled prior to the application of the suspension to the substrate such as by the incorporation of a sol of a polyvalent metal oxide or solution of a salt of a polyvalent metal into the suspension. |
