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 milliampssq 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
