Novel carbon-ion fuel cells. Quarterly technical report, April--June 1996
This report presents research to develop a new type of of fuel cell using a solid electrolyte that transports carbon ions. This new class of fuel cell would use solid C dissolved in molten metal (carbide) as a fuel reservoir and anode; thus expensive gas or liquid fuel would not be required. Thermodynamic efficiency of carbon-ion fuel cells is reviewed, as are electrolyte crystal structures (oxide and fluorite carbides). The sequence of laboratory research procedures for developing a solid C-ion electrolyte and to determine the ionic conductivity of C ions therein is outlined; results of the laboratory research to date are summarized, including XRD analysis of crystal structures and transition temperatures of carbides (La, Ce, Be, Al) and SIMS of carbon isotopes.
