Energy savings by means of fuel cell electrodes in electro-chemical industries. Progress report, August 1, 1979-October 31, 1979
Description: Initial efforts in studies of the effects of fuel cell electrodes on energy savings in electrochemical processes have been directed toward assembling test hardware and evaluation of a new zinc plant feed. A complete chemical analysis of the feed is reported. Utilizing the 2'' x 2'' (active electrode area) hardware and techniques developed under Contract No. ET-78-C-02-4881, 6 h zinc electrowinning tests demonstrated a current efficiency of greater than 90% with an energy consumption of 0.54 to 0.55 kWh/lb of zinc. For these tests, 0.1 g/l gelatin was employed as an electrolyte additive and the resultant zinc plates were bright, smooth and compact.
