The present state of development of anode-supported solid oxide fuel cells may be considered sufficient for commercialization of the technology. However, fabrication of the SOFC stacks faces some issues related to materials science and efficiency of the transition from electrochemical performance of the single cell to performance of the whole stack. A patent-based overview of stack design demonstrated that evolution of industrial-grade SOFCs has moved on from sophisticated processes like enhanced chemical vapor deposition (ECVD) from Siemens Westinghouse to much more materially minded solutions, based on tape casting, screen-printing, milling and stamping of the steels, and sealing with glass- and mica-based composites. Noble metals and precise-fabricated ceramic parts are being replaced with steels, protected from oxidation by fine-tuned alloying and covered with functional layers which compensate for the weaknesses of this approach. This chapter focuses on the following key points: general design of recent stacks, high-temperature sealing, special Cr-alloyed ferritic steels for interconnects and structural elements, functional layers (chromium barriers and cathode contact helpers), and characterization procedures of whole stack performance. A propos the last point, this is considered mainly from the electric/electrochemical point of view and includes issues related to accelerated testing and monitoring in operandi. All these topics are absolutely crucial and require far greater involvement and analysis by experts in the particular fields. The main mission of this book meanwhile is to report on the current state of SOFC-based design in the context of the micro-CHP.
