Claims20
A gas diffusion electrode comprising an electrically conductive web provided on at least one side thereof with a coating containing a rhodium--rhodium oxide catalyst on a carbon black support.
A method for preparing rhodium--rhodium oxide catalyst by dissolving a rhodium chloride salt in a solution with carbon black, precipitating the metal by raising the pH, filtering the solids, drying and heat-treating the remaining solids under argon at 600.degree. C.
A method for preparing high surface area rhodium--rhodium oxide catalyst by dissolving rhodium chloride salt in a solution with carbon black, precipitating the metal by raising the pH, filtering the solids, drying, and heat treating the remaining solids under argon at 600.degree. C.
A method for preparing high surface area rhodium--rhodium oxide catalyst by dissolving a rhodium chloride salt in a solution with carbon black, precipitating the metal by raising the pH, filtering the solids, drying, and slowly burning off the carbon in an air-filled oven at 300.degree. C.
A composition of rhodium--rhodium oxide supported on carbon black for use in gas diffusion electrodes.
