ABSTRACT:
A gas diffusive electrode, an electrochemical device employing same, and methods of manufacturing and using same are provided. The gas diffusive electrode includes platinum powder and carbon powder or grain, to which carbon powder or grain whose particles are provided with a water-repellent film is further mixed. The gas diffusive electrode maintains an enhanced gas permeability.
