the purpose of this research program is the demonstration of the technical feasibility of a high-temperature, solid-electrolyte fuel cell, building on the presently-existing technological base. the bulk of the work consists of identifying and selecting candidate component materials, fabricating cells and cell stacks from these materials, and testing these cells and cell stacks under conditions which might be expected in operation. the major emphasis is on the invention and fabrication of an interconnection film. emphasis is also being placed on the fabrication of porous support tubes of calcia-stabilized zirconia, to the desired specifications of tensile strength, porosity, surface finish, and purity. concurrently, tubes will be prepared in-house and, if necessary, will also be purchased from commercial suppliers and evaluated for compliance. the overall technical effort is aimed at achieving 5 milestones in the 2 year period of the contract. these include: (1) identifying and selecting new candidate interconnection materials; (2) preparing porous support tubes to desired specifications; (3) demonstrating acceptable test performance in identified interconnection material(s) and (5) in cell stacks. progress is reported
