The free energy available in the process of mixing river water and seawater corresponds to a power head of about 250 m. A dialytic battery with ion-exchange membranes can directly convert this salinity difference energy into the electric energy. In the present study, a new system of the solar membrane cell has been proposed in which the dialytic battery is coupled with the solar still. In this system (abbreviated as SMC) the solar energy is stored through the solar still as the salinity difference energy between fresh water and concentrated seawater, and by the dialytic battery it is converted into the electricity according to demand.A laboratory scale SMC has been constructed and its performance was tested ; Especially, three types of dialytic battery with different scale has been tested in order to investigate the scale up effect of the dialytic battery. The open circuit potential V_0, and the power output W have been measured as functions of fresh water flow rates and the operating temperature ; from these measurements, the maximum power W_<max> and the internal resistance of the battery were determined. The power became several times larger than that produced under ordinary conditions. In the largest dialytic battery (number of membrane pairs is 200 and the effective area of membrane is 475 cm^2), V_0 and W_<max> reached upward of 10 V and 1000 mW.Tests results have been compared with those obtained from the calculated on the basis of a numerical model. It was shown that the test results were in good agreement with the calculated.

在河水和海水混合过程中可用的自由能对应于约250 m的动力压头。具有离子交换膜的透析电池可以直接将这种盐度差能量转化为电能。在本研究中，提出了一种新的太阳能膜电池系统，其中透析电池与太阳能蒸馏器耦合。在该系统中（简称SMC）将太阳能通过太阳能蒸馏器作为淡水和浓海水的盐度差能量储存起来，再由透析电池根据需要将其转化为电能。特别地，为了考察透析电池的放大效果，对三种不同规模的透析电池进行了测试。测量了开路电位V_0和输出功率W随淡水流速和工作温度的变化，并由此确定了电池的最大功率W<max>和内阻。能量比正常情况下产生的能量大几倍。在最大的透析电池（膜对数为200，膜有效面积为475 cm ~ 2）中，V_0和<max>W_1分别达到10 V和1000 mW以上。试验结果与计算结果吻合较好。
