氯化锂溶液为工质的溶液浓差发电实验研究
Experimental study of solution concentration difference power generation with lithium chloride solution as working fluid
摘要
Abstract
Through experiments,the influences of concentration variations of both weak and strong solutions on the characteristic parameters of reverse electrodialysis cells (REDCs ),such as open circuit voltage (OCV),internal resistance and power density,are explored,in which lithium chloride solution prepared is used as working fluid.The results show that the maximal OCV and power density of the homemade REDCs with 10 cells are 1.88 V and 1.67 W/m2 in the range of experimental concentration,respectively.The OCV of the REDCs reduces with the increase of weak solution concentration,but increases first and then reduces with the increase of strong solution concentration. The internal resistances of the REDCs reduce with the increase of both weak and strong solution concentrations.The terminal voltage and power density of the REDCs are affected by current.With the increase of current,the terminal voltage drops linearly but the variations of power density appear a convex quadratic curve.The power density of the REDCs reaches maximum when the total circuit resistance is twice as big as the internal resistance of the REDCs.关键词
