Gas diffusion electrode comprises at least a carrier, which is electrically conductive, and a porous coating on an electrochemically active catalyst and a hydrophobic material. The electrode has a gas containing the oxygen and a side facing the alkaline electrolyte. The catalyst as a catalytically active component has a precious metal silver (preferred) or platinum. The hydrophobic material is a hydrophobic polymer. The catalyst containing coating has a pore volume of 10-500 mm 3>/g, preferably 50-200 mm 3>/g and a pore diameter of 100-10000 m, preferably 600-6000 m.
