OSTI ID:10179175

Commercial systems are envisaged to encompass the range from a few hundred kW to megawatts, with applications for total energy systems in commercial buildings and electric power units operating on coal derived gas. The solid oxide fuel cell comprises a porous Ca0-stabilized zirconia tube, a mm layer of La manganite that provides the air (positive) electrode, a solid electrolyte (oxygen ion conductor) layer of yttria-doped zirconia, an interconnection layer of La chromite, and a nickel cermet fuel (negative) electrode. Active length of the cells is up to 70ds cm. Technical effort is organized under 3 technical tasks with the objectives of defining a reference design, improving and verifying cell performance, and developing and verifying stack performance for a 25 to 200 kW generator. 7 figs, 3 tabs, 3 refs.
