MOLTEN-CARBONATE FUEL BATTERY PROGRAM

Abstract

Power obtainable from single cells on hydrogen fuel using the 4 3/16 in. electrode diameter assembly was increased from an average of 60 to 100 w/sq ft at 0.7 v by improvements in the fuel electrode structure and reduction in electrical resistance. These cells produce approximately 60 w/sq ft at 0.5 v on a fuel composed of 50:50 H and CO2; cells have operated for more than 1000 hrs. A concentration of 0.2 mole percent of H2S in the fuel gas was not detrimental in a 1000 hr test. A 100-w battery design has been constructed. A laboratory model of the JP-4 air partial oxidation unit has produced 12.5 cu ft/hr of a gas stream containing 50-60% gaseous fuel (mostly H and CO), 35-40% N, and 5- 10% CO2. This unit has been operated for 78 continuous hrs. A cell has been operated directly on the gaseous product. Additives for the molten-carbonate electrolyte were screened, (Na2MoO4, Na2CrO4, Na2WO4, Na2S, and Na2ZnO2). Only sodium sulfide was observed to have a significant positive effect on cell power output.
