Abstract
This chapter consists of two sections, ‘Power Generation Efficiency of Photovoltaics and a SOFC-PEFC Combined Microgrid with Time Shift Utilization of the SOFC Exhaust Heat’ and ‘Power Generation Efficiency of an SOFC-PEFC Combined System with Time Shift Utilization of SOFC Exhaust Heat’. The 1st section proposes the combined system of a solid-oxide fuel cell (SOFC) and a proton-exchange membrane fuel cell (PEFC). The proposed system consists of a SOFC-PEFC combined system and a photovoltaic system (PV) as the energy supplied to a microgrid. The 2nd section studies a microgrid by introducing a combined SOFC and PEFC. This study investigates the operation of a SOFC-PEFC combined system, with time shift operation of reformed gas, into a microgrid with 30 houses in Sapporo, Japan.
