摘要(Abstract)：

余热吸收制冷与逆电渗析耦合式冷-电联产系统中，工作溶液特性对系统能量转换影响显著。为了评估真实吸收式制冷系统中实际存在的添加剂对于逆电渗析性能的影响，文中建立逆电渗析电堆实验台，分别以工作溶液中的溴化锂浓度、钼酸锂浓度、异辛醇浓度为变量，实测不同条件下的输出电流-电压关系，得出对应功率密度变化规律。结果表明，首先，浓、稀溴化锂溶液盐度梯度越高，功率密度越大，发电性能越好。其次，当钼酸锂质量分数极低时，逆电渗析电堆的发电性能被抑制(例如添加量为0.3%时的性能不如0.1%时)；随着钼酸锂添加量的增加，抑制作用减弱，开路电压有所回升(例如添加量为0.5%时优于0.3%时)。最后，添加体积分数≤0.15%的少量异辛醇会促进逆电渗析电堆的发电性能；但添加量较高时，则表现出明显的抑制作用。研究结论为后续吸收式制冷与逆电渗析耦合的闭式热-电-冷转换系统发展提供参考。
