This patent consists of a gas diffusion composite electrode useful in an electrochemical cell. The electrode consists of an electrochemically active layer and a backing layer, the active layer characterized as porous, homogeneous, hydrophilic, and electrolyte-permeable. It also consists of a sintered mixture of a major amount of an electrically conductive, hydrophilic, particulate material admixed with an electrochemically active catalyst, and a minor amount of a hydrophobic polymer. The particulate material is substantially coated with the hydrophobic polymer by precipitation of the hydrophobic polymer upon the particulate material.
