Abstract
A gas diffusion composite electrode useful in an electrochemical cell comprising an electrochemically active layer and a backing layer, said active layer characterized as porous, homogeneous, hydrophilic, and electrolyte-permeable and comprising a sintered mixture of a major amount of an electrically conductive, hydrophilic, particulate material containing admixed therewith an electrochemically active catalyst, and a minor amount of a hydrophobic polymer, said particulate material being substantially coated with said hydrophobic polymer by precipitation of said hydrophobic polymer upon said particulate material.
