Summary

The most important design criteria for power generators based on Solid Oxide Fuel Cells (SOFC) with regard to the different applications are discussed. The emphasis is put on the requirements of the specific type of application (stationary, transportation, portable) and stack materials and design and the interdependency thereof. Two critical issues required from SOFC generators are thermo-mechanical stability — in particular with regard to thermal cycling — and long-term stability of the electrochemical performance. Design principles which help to prevent or reduce mechanical stresses are discussed.
