构建了具有太阳能蓄能功能的零排放分布式能量系统.并进行了运行参数优化和性能分析.该系统将槽式集热器吸收的太阳能和甲醇作为能量的输入,利用甲醇水蒸气重整制取清洁的氢源,以连续不间断的质子交换膜燃料电池发电作为分布式系统的能量输出.通过效值仿真分析,研究了不同水醇比、太阳辐射强度、进料速度等运行参数对太阳能-甲醇制氢产率的影响规律.在原料等量的情况下,比较了独立运行的直接甲醇燃料电池和太阳能热发电的总发电量与该集成系统的发电量,并分析了太阳能辐射强度变化对集成系统效率的影响.
A zero-emission distributed energy system with solar energy storage function was constructed, and the optimization of operating parameters and performance analysis were carried out.The solar energy and methanol absorbed by trough collector were used as the input of energy, and methanol steam reforming Take a clean hydrogen source, continuous continuous proton exchange membrane fuel cell power generation as a distributed system energy output.Through the simulation analysis of efficiency, the effects of different water-alcohol ratio, solar radiation intensity, feed rate and other operating parameters on solar energy - methanol production rate of hydrogen in the case of the same amount of raw materials, the independent operation of direct methanol fuel cells and solar thermal power generation compared with the total power generation of the integrated system, and analysis of solar radiation intensity changes Impact on the efficiency of integrated systems.
