The report gives results of the first phase of a study of the feasibility of using coal to produce electricity directly in a fuel cell that uses a molten-carbonate electrolyte, a coal anode, and an air cathode. The cell voltage, the polarization of the anode, and the nature of the gaseous products formed were investigated. Electrodes made from charred coal yielded open-circuit voltages close to 1 V. At 975 K, the activation plus concentration polarization was about 200 mV at current densities of 100 mA per sq cm and larger. At higher temperatures smaller polarizations were observed. The gaseous anode products were primarily CO2, with some CO. Current efficiencies were somewhat less than 100 percent. The low values were possibly due to losses of anode gases by mechanical means. Coal ash added to the molten electrolyte did not appear to be deleterious to cell operation. Descriptions of possible future engineering systems and thermodynamic limitations are presented.
