Abstract

Abstract:

The present work experimentally investigates the use of five pure salt solutions as working solution in a lab-scale reverse electrodialysis (RED) stack. The main performance parameters of RED stack were analyzed in terms of open circuit voltage (OCV), stack ohm-resistance and power density. Effect of two concentration gradients (3/0.05 and 5/0.05) was investigated. Results show that the electrolyte solution with high electric conductivity is good to reduce stack ohm-resistance. The experimental lowest stack resistance of 2.8Ω was measured when using NH₄Br solution at concentration of 5/0.05, meanwhile, the experimental lowest OCV reached at 1.355V. Because the permselectivity of ion-exchange membranes is weakened at high concentration. The experimental highest OCV of 1.929V was measured when using KAc solution at concentration of 5/0.05, which is about 9% higher than the OCV in LiCl at the same concentration. Due to 17% lower resistance, the latter achieved the maximum power density of 2.217W/m². The OCV in NaAc is slightly lower than that in KAc, but the latter internal resistance is too high, which makes the latter maximum power density minimum.

摘要：

以5种工质盐溶液作为逆电渗析堆（RED）的工作溶液，分别在两种浓度（mol/L）比（3/0.05、5/0.05）下，分析逆电渗析堆主要工作特性参数：开路电压、电堆欧姆内阻以及功率密度。实验结果表明：电导率高的电解质溶液为工质时，电堆内阻降低，实验中以浓度比5/0.05溴化铵溶液为工质的电堆具有最低的欧姆内阻（2.80Ω），同时电堆开路电压也最低（1.355V）。因为过高的溶液浓度梯度降低了离子交换膜的离子选择透过性。浓度比5/0.05乙酸钾溶液为工质的电堆具有高的开路电压，达到1.929V，比氯化锂溶液高6.9%，但其电堆内阻比氯化锂溶液高17%，以氯化锂溶液为工质的电堆输出的最大功率密度达到2.217W/m²。以乙酸钠溶液为工质开路电压比乙酸钾稍低，但其内阻过高，使得输出的最大功率密度最小。
