This report describes molten carbonate fuel cell research and development activity at General Electric Company during the three month period beginning 15 May 1978 and ending 15 August 1978. The objectives of this Phase I effort include the development of promising concepts to circumvent a number of outstanding technical challenges in molten carbonate fuel cell technology and the better definition of the operating limits of molten carbonate fuel cells and power plants based thereupon. During the fourth quarter of the program, principal activities have been the development of an analytical fuel cell model, the operation of experimental molten carbonate fuel cells using pure and H/sub 2/S-contaminated fuels which simulate coal-derived fuels, and the development of synthesis and fabrication techniques for the electrolyte tile and electrode cell components. Specific accomplishments include the testing of cells for the purpose of improving and evaluating cell design features, corrosion resistance, electrolyte tile performance, electrode performance, and the tolerance of cells toward fuels containing up to 1000 ppM H/sub 2/S. A new synthetic route to the preparation of tile-quality, electrolyte-free LiAlO/sub 2/ has been developed. Functioning electrolyte tiles have been prepared for the first time by a non-hot-pressing fabrication technique. The necessary inventory of cells and cell components has been maintained.
