Abstract:

Although cyanamide may be useful as an acid for organic nitro compounds in a voltaic cell, the advantages sought are insufficient to warrant further effort at this time. Metal nitride reference electrodes were tested in hardware-cell assemblies, but no suitable electrolyte separator has yet been devised to permit reproducible and stable operation. A study was begun of limiting potentials for redox reactions in NH3 electrolytes on various electronically conducting substrates cathectors, such as Pt, Ag, Ni, stainless steel, and pyrolytic graphite. Tests also began on several types of porous conductive cathector matrices. Study began on soluble fuel-cell reactants, such as solutions of sulfur and organic nitro compounds in anhydrous ammonia. A Li-S fuel cell could be made with both electrode reactants in solution. This cell has a high theoretical enersity of 11 Jmg, as compared with 12 Jmg for the H2-O2 fuel-cell couple both exceed 1000 Wh1b. Preliminary coulometric reduction of S in concentrated NaSCN-NH3 solution showed the expected two-electron total reaction occurred at low rate. Cyclic voltammetric measurements of reduction potentials of S solutions on Hg or Pt surface have been satisfactory, because of interfering reactions. Author
