This paper examines aspects of fuel cell system design for application in stationary residential markets. The development of fuel cell systems for sub-10 kW stationary applications involves consideration of sizing, fuel processing, operating point selection, fuel cell operating capabilities, system integration, and load management strategies. Each of these considerations is discussed, and strategies are presented for matching the electrical and thermal energy demands of a residence with a solid oxide fuel cell power system. Efficiency considerations for configuring fuel cell, DC-to-AC inverter, and electrical energy storage components for conditioning of DC power generated by the fuel cell stack are also given. Recommendations are made on the potential opportunities for solid oxide fuel cells in small-scale stationary power applications.
