将太阳能光伏光热综合利用技术（PV/T）与质子交换膜电解水制氢技术（PEMWE）结合,提出基于PV/T的质子交换膜电解制氢系统（PV/T-PEMWE）。系统由PV/T模块与PEM电解槽通过耦合而集成,建立数学模型分析其在白天的动态光电光热性能及制氢性能,并在相同条件下将其性能与光伏电解制氢系统（PV-PEMWE）进行对比。结果表明：PV/T系统全天总发电量为0.5 kWh,电效率维持在13%~15%之间,总发热量为9.4 MJ,热效率维持在30%~40%之间;PV/T-PEMWE系统制氢效率高于PV-PEMWE系统,PV/T-PEMWE系统全天的制氢量为153 L,平均制氢速率约为19 L/h。
Abstract
Combining solar photovoltaic photothermal comprehensive utilization technology （PV/T） with proton exchange membrane electrolysis water electrolysis technology （PEMWE）, a PV/T-based on PEMWE system （PV/T-PEMWE） is proposed. PV/T module and PEM electrolyzer are integrated through coupling, a mathematical model is established to analyze the dynamic photoelectric photothermal performance and hydrogen production performance of the system during the day, and its performance is compared with photovoltaic electrolytic hydrogen production system （PV-PEMWE） under the same conditions. The results show that the total power generation of the PV/T system is 0.5 kWh throughout the day, the electrical efficiency is maintained at 13%-15%, the total calorific value is 9.4 MJ, the thermal efficiency is maintained at 30%-40%. The hydrogen production efficiency of PV/T-PEMWE system is higher than that of PV-PEMWE system. The PV/T-PEMWE system can produce 153 L of hydrogen throughout the day, and the average hydrogen production rate is about 19 L/h.
