摘要
提出了一种基于太阳能、电解槽、燃料电池的热电氢多联供的分布式能源系统,建立了系统的数学模型,分析了电流密度、工作温度、辐射强度等运行参数对系统热力学性能的影响.结果表明:较高的辐射强度、运行温度和较低的电流密度有利于提高系统效率,系统的联供效率和制氢效率分别可达到44%和32%.
A distributed energy system with heat power and hydrogen multi-generation based on solar energy is proposed.The mathematical model of the system is established.The effects of current density,working temperature,radiation intensity and other operating parameters on the thermodynamics performance of the system are analyzed.The results show that high radiation intensity,operating temperature and low current density are beneficial to improve the efficiency of the system.The system's multi-supply efficiency and hydrogen production efficiency are 44% and 32% respectively.
