Design, fabrication and testing of a solid oxide fuel cell stack for a 25 kW to 200 kW generator

Technical Report · Wed Mar 01 04:00:00 EST 1989

OSTI ID:7145533

The effort reported herein was carried out over the period April 1988 through March 1989. Prior effort under the contract covered the period since June 1980 and culminated in placing an test a 6 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 9000 hours, and a 24 cell ({approximately}400 watts) submodule that was operated successfully for more than 2000 hours. The first two years of effort under the present phase of the contract was reported in annual reports. The technical effort in the current modification is organized under three technical tasks that have objectives as follows: 1. To define a reference designs 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. In addition, post test analyses of the 5 kW generator have continued during this reporting period. A total of 360 cells were operated in the two tests of the 5 kW generator. These, along with components of the modules provide operating results from a wide range of in-module conditions.
