英文摘要：
Based on the principle of electrochemical reaction and analysis method of thermodynamics, this paper studies the power generation mechanism of Solid Oxide Fuel Cell （SOFC）. On the base of the principle of electrochemical reaction, SOFC system modes were established, effects of electrochemical parameters on the system performance of SOFC were analyzed and the power generation mechanism of SOFC from chemical energy to electricity energy by a non-thermodynamic mode was revealed. The -effects of thermodynamic parameters on the SOFC system performance were also studied. The main ways of improving the SOFC system performance are proposed and the potential of enhancing the total hybrid power system performance by integrating SOFC with advanced thermal cycle system are revealed. Above research achievements will provide valuable reference for further study on SOFC hybrid power system with high efficiency.
