가스터빈/용융탄산염 연료전지 하이브리드 시스템의 성능해석

초록

Design performance of a hybrid power generation system, comprised of a gas turbine and an atmospheric pressure molten carbonate fuel cell, has been analyzed. A reference calculation was performed for the design condition of a system under development and the simulated results agree well with the published data. The effects of turbine inlet temperature and pressure ratio on system performance and the operating temperature of the fuel cell were analyzed. Influences of other main design parameters on the system performance have been examined including fuel utilization and current density of the fuel cell and heat exchange effectiveness of the heat recovery unit.
