This chapter deals with micro-cogenerative power system based on solid oxide fuel cells. Such systems are composed of several devices and machines which operate at temperatures ranging from 20 to 1000 ℃ or more. The challenges related to thermal and electrical integration of such systems are discussed. The alternative configurations of micro-CHP units based on SOFCs are presented in this chapter. The authors present the key issues related to the components of a system with electric power output of 2000 W and thermal power of up to 2000 W. This is followed by a discussion on the technical measures required to achieve proper electrical and thermal integration of the system. A power unit designed, constructed, and operated in the Institute of Power Engineering (Poland) is discussed in detail. Key aspects of the design and its functionality are described, followed by a presentation of a typical heating profile of the micro-cogenerator. Some of the unique features of the system, including the dual start-up module, are described in depth. Differences and challenges related to the use of either the electric heaters or the auxiliary start-up burner are discussed. A conceptual schematic chart, visualization of the unit, and its actual final form are presented, followed by a demonstration of the temperature characteristics of the main components once the system achieves a quasi-steady-state mode of operation. The system presented in this chapter is a first-of-its-kind unit constructed in Poland producing electricity and usable heat in SOFCs.
