Modeling of SOFC-Based Power Systems

Chapter
Part of the Green Energy and Technology book series (GREEN)

Abstract

Chapter  1 introduces the topic of solid oxide fuel cells, setting out the principles of operation and the governing equations used to compute the balances. Depending on the level of detail required, these equations can be reduced to discrete forms, can be simplified under certain assumptions or substituted by alternative mathematical descriptions. Some modeling techniques go as far as omitting the equations altogether. Alternative methods are often proposed to predict cell and stack performance and perform mass, energy, and charge balances instead of using a purely analytical approach and the governing equations. This chapter looks at the different modeling approaches and discusses the method which was found to be best suited to system-level studies in SOFC-based power systems. Development of a SOFC-based power units is usually an iterative procedure in which modeling is coupled with a conceptual phase which includes a definition of the design. This chapter will present different modeling methods applicable to SOFC-based power systems. Selected approaches are discussed and evaluated for the purpose of analysis of a micro-CHP unit with SOFCs. It also highlights the main parameters affecting the performance of SOFC stacks.
