Abstract
A powerful hydrogen azide-oxygen fuel cell can be obtained by passing an aqueous solution of Hydrogen Azide (not to exceed 30% by weight) and Sodium Sulphate over a platinized electrode which forms the anode (-) of the fuel cell. Oxidation takes place at the cathode (+) by the introduction of Oxygen over a platinized electrode. The azide (N.sub.3) radical looses electrons and forms gaseous nitrogen while the oxygen atom picks up the electrons, in the presence of platinum, and forms water with the surplus hydrogen atoms (H.sup.+) present. The measured cell voltage is 5 volts.
