Research on Electrochemical Energy Conversion Systems.
Abstract
The investigation of electrochemical energy conversion systems has involved work on three tasks. The first deal with high energy galvanic cells of the type applicable to vehicle propulsion. Attention has been directed toward the cathode depolarizer problem, particularly the mechanism of reduction of the benzofuroxan type structure. Progress has been made in developing methods for identifying and separating benzofuroxan from its reduction products. An improved method for the determination of water in organic electrolytes has been developed. This method, based on the lead tetraacetate reaction, is more sensitive and accurate in the 0 to 100 ppm range than present methods. The second task deal with the mathematical analysis of electrochemical energy conversion processes. The Hartley regression method has been applied to the Volmer equation describing the net current at an electrode during an activation controlled process. The method appears to offer a method of calculating the kinetic parameters without using the questionable assumptions made in the Tafel type of treatment. The third task, of an exploratory nature, investigated solid, low temperature, proton conductors. Preliminary experiments to duplicate the claims of a French patent have been unsuccessful. (Author)
