Abstract : An electrolyte material with a resistivity less than one-fifth th t of (ZrO2)0.85(CaO)0.15 was discovered. Various methods for applying electrodes to the electrolyte were tried; standard procedures were worked out for evaluating these electrodes. A systematic program for finding an optimum electrode was prepared. Three methods of sealing cells were investigated so that large systems can be fabricated. More work remains to be done in this area. A number of cell tests were carried out to determine the performance of electrolytes, electrodes and seals. The experimental cells and cell systems revealed much concerning the basic phenomena associated with solid electrolyte fuel cells. They have demonstrated problems which must be solved in order to produce a practical power syste . The experience with these cells makes it seem reasonable to predict that solid el ctrolyte fuel cell systems can be built which will produce 125 watt/lb sub m and 400 watt/cu ft and will last over 600 hours.
