摘      要：Syngas fuel generated by solar energy integrating with fuel cell technology is one of the promising methods for future green energy solutions to carbon *** paper designs a novel solar-driven solid oxide electrolyzer system integrated with waste heat for syngas *** photovoltaic and parabolic trough collecter together drive the solid oxide electrolysis cell to improve system *** thermodynamic models of components are established,and the energy,exergy,and exergoeconomic analysis are conducted to evaluate the system’s *** the design work conditions,the solar photovoltaic accounts for 88.46%of total exergy destruction caused by its less conversion *** exergoeconomic analysis indicates that the fuel cell component has a high exergoeconomic factor of 89.56%due to the large capital investment *** impacts of key parameters such as current density,operating temperature,pressure and mole fraction on system performances are *** results demonstrate that the optimal energy and exergy efficiencies are achieved at 19.04%and 19.90%when the temperature,pressure,and molar fraction of H_(2)O are 1223.15 K,0.1 MPa,and 50%,respectively.
