提出一种基于生物柴油重整的燃料电池发电系统
通过建模仿真计算
研究水碳比、蒸汽重整温度、燃料电池燃料利用率等参数对系统性能的影响
并基于优化算法得到系统最佳工作点。结果表明:降低水碳比会同时提高重整气内H2和CO浓度;提高燃料电池燃料利用率能够有效提高系统效率
但过高燃料利用率会产生用于进料预热的额外功率损耗;发电系统额定功率下的最大工作效率为42.21%
在耗油率和碳排放量方面相较柴油发动机均有较大改善。
The paper proposes a fuel cell power generation system based on biodiesel reforming. The effects of parameters such as water-carbon ratio
steam reforming temperature
and fuel cell fuel utilization rate on the system performance are investigated through modelling and simulation calculations. Afterwards
the optimal working point of the system is obtained based on an optimization algorithm. The results show that: lowering the steam-carbon ratio increases both H and CO concentrations in the reformed gas; increasing the fuel utilization rate of the fuel cell effectively improves the system efficiency
but excessively high a fuel utilization rate results in additional power loss for feed preheating; the maximum efficiency of the power generation system at rated power is 42.21%
and the power generation system has improved in terms of fuel consumption and carbon emission compared with the diesel engine.
