摘要：
The paper builds a membrane reactor reforming hydrogen production and fuel cell power generation system model by Aspen plus. According to the change of direct solar radiation intensity DNI on a certain day in Lhasa, the available energy of solar energy is calculated and used as an external heat source to input the fuel cell power generation system. The effects of reaction temperature, steamto- carbon ratio(S/C)and the solar direct normal irradiance( DNI )on the performance indicators of the system are analyzed. The performance indicators include methane conversion rate, H2 product yield, output power and voltage of fuel cell, the solar- chemical energy conversion efficiency. The results show that when the reaction temperature is 500 ℃ and the S/C is 2.5, it is conducive to solar methane reforming. The daily system performance results show that from 10 am to 20 pm on a typical day, the system output power is 120 kW, the solar-chemical energy conversion efficiency is 0.368, and the system power generation efficiency is 0.225. © 2022, Solar Energy Periodical Office Co., Ltd.
