摘　　要：盐差能广泛存在于海水与淡水之间,作为一种新型能源。反电渗析法是一种将盐差能转换为电能的方法。本文通过改变两股溶液的流速以及放电电流,来研究不同进液速度和放电电流对输出电压以及功率密度的影响。结果表明随着进液速度的增加输出电压和功率密度也随之增加;随着放电电流的增加,输出电压减小,输出功率先增加后减小。Salinity gradient energy as a new type of energy widely exists between seawater and freshwater. Reverse electrodialysis（RED） is a process that transfers the salinity gradient to energy. In this paper, effect of different inlet velocity and discharge current on the output voltage and power density was studied by changing the flow velocity and the discharge current of the two solutions. The results show that the output voltage and power density increase as the inlet velocity goes up; the output voltage drops as the discharge current increases, the output power density increases firstly and then decreases.
