摘要

•A 2D SOEC model for dynamic behavior analysis is developed.•The model employs real-time photovoltaic power supply for co-electrolysis.•A high CO2 mole fraction can help inhibit temperature fluctuation.•The inlet gas temperature has little effect on H2/CO ratio at high voltages.•Output H2/CO ratio of 60% gas utilization is higher than that of 80%.
