The effort reported herein was carried out over the period from March 1986 through December 1990, modifications (A030 through A056) to Contract DE-AC21-17089 (prior number: DE-AC02-17089), The High Temperature Solid Oxide Electrolyte Fuel Cell Power Generation System. Prior effort under the contract covered the period since June 1980 and culminated in placing on test a 5 kilowatt (kW) generator. Intermediate steps included testing of many materials and single cells ([approximately]15 watts), a three cell bundle ([approximately]45 watts) that was operated successfully for nearly 9000 hours, and a 24 cell ([approximately]400 watts) submodule that was operated successfully for more than 2000 hours. The technical effort in the current modification is organized under three technical tasks that have objectives as follows: (1) To define a reference design, subsystem design, and component requirements for a tubular solid oxide fuel cell plant with the greatest potential to be commercialized; (2) To develop and verify cell performance, which satisfies the component requirements; and, (3) To develop and verify stack performance, which satisfies the component requirements.
