High efficiency solid oxide fuel cell—internal combustion engine hybrid power system

摘要

A hybrid stationary power generator is provided. The system is fueled from natural gas and based on SOFCs and high efficiency, internal combustion (IC) engine technologies is conceived to generate electric power at 100-kW scale with an efficiency of 71% and a capital cost of <900 $/kW. This novel system integrates a solid oxide fuel cell (SOFC) stack with a high efficiency stationary engine and balance-of-plant (BOP) equipment to create a hybrid power system.
