The metal-supported solid oxide fuel cell (SOFC) was studied. Hydrocarbon fueled operation was used to make SOFC system. Different operating characteristics for metal-supported SOFC are used than for conventional ones. Metal-supported SOFC was successfully fabricated by a high temperature sinter-joining method and the cathode was in-situ sintered. Synthetic gas, which is compounded as the diesel reformate gas composition and low hydrocarbons was completely removed by the diesel reformer. Metal-supported SOFC with synthetic gas was operated and evaluated and its characteristics analyzed. The performance of hydrogen operation shows 0.4 W·cm−2 of maximum power density. The maximum power density of the synthetic gas operation decreased to 0.22 W·cm−2 and to 0.11 W·cm−2 after 10 hours operation, respectively. Degradation occurred because a large steam quantity made an oxidation atmosphere at high temperature, causing the metallic part damage.

To both increase the power density of a tubular solid oxide fuel cell (SOFC) and maintain its beneficial feature of secure sealing, a flat-tube high power density (HPD) solid oxide fuel cell is under development by Siemens Westinghouse, based on their formerly developed tubular model. In this paper, a three dimensional numerical model to simulate the steady state heat transfer and fluid flow of a flat-tube HPD–SOFC is developed. A computer code is programmed using the FORTRAN language to solve the governing equations for continuity, momentum, and energy conservation. The highly coupled temperature and flow fields of the air stream and the fuel stream inside and outside a typical channel of a one-rib flat-tube HPD–SOFC are investigated. This heat transfer and fluid flow results will be used to simulate the overall performance of a flat-tube HPD–SOFC in the near future, and to help optimize the design and operation of a SOFC stack in practical applications.
