Work proceeded this quarter under three program tasks. Under Task 1.0, work was completed on the reference power plant design description. Under Task 2.0, work continued on the development of materials, anode, cathode and electrolyte, and on stack design and analysis. Long term corrosion tests of current collector alloy specimens continued, with 310SS, GE2541 and Aggalloy showing adherent scale formation in the cathode gas atmosphere after 7000 hours. A number of alternate cathode materials were fabricated and tested for conductivity, solubility and stability. A new conductivity measurement device has been partially constructed. Under Task 4.0, testing of the effects of hydrocarbons in the fuel on the operation of carbonate fuel cells was completed. This series of tests has shown that small amounts of organic compounds do not adversely affect fuel cell operation. Testing of a cell with H/sub 2/S contamination in the fuel has proceeded for over 1700 hours. Cell performance decreased with increasing concentrations of H/sub 2/S, as would be expected, but also recovered substantially when clean fuel gas was introduced for a period of 378 hours. (WHK)
