PRELIMINARY INVESTIGATIONS OF POROUS FLOWTHROUGH ELECTRODES OF PLATINUM BLACK,

Abstract

Half cell studies were made on four fuels and two ooxidants, using a porous flow-through electrode system. The electrode studied consisted of a sandwich of platinum black between platinum screens. The fuels tested were methanol, hydrazine, ammonia and potassium borohydride; the oxidants tested were hydrogen peroxide and nitric acid. All of the reactants were capable of producing current densities of several hundred milliamps/sq cm at reasonable voltages, but hydrogen peroxide suffered from instability. The results were qualitatively in agreement with the simple theory of porous flow-through electrodes, but were not in quantitative agreement. Some discussion of the reasons for departure from the theory are given. A later report will investigate one fuel in more detail in order to clarify the theory of operation. (Author)
