Design and Development of SOFC Stacks

Solid oxide fuel cell stack consists of three components, mainly including single cell, interconnect, and sealant. The interface contact between the interconnect and the cell is one of the most important factors on the stack output performance of solid oxide fuel cell besides the above three components. In this chapter, several contact models between the interconnect and the cell are designed and verified by assembling stacks. The mechanism of interface on stack performance is also analyzed. High output power density and high stability of solid oxide fuel cell stack are developed and tested by the optimized interface design.
