Power generation by reverse electrodialysis in AAO nanochannel array with CVD deposited SiO2, Si3N4 layer
초록/요약
It have been conducted that studies of reverse electrodialysis to convert into electric energy by using a polymer ion-exchange membrane from Gibbs energy dissipated when the seawater and fresh water are mixed. Recently, studies using solid nanochannels to improve the efficiency of the reverse electrodialysis is in progress. Especially study of porous alumina thin film is concentrated. In this study, SiO2 and Si3N4 was deposited on AAO by CVD for improving the ion-selectivity. We tried to measure the resistances and Open Circuit Voltages for various deposition thicknesses of SiO2 and Si3N4. SiO2 with 1μm and Si3N4 with 1μm thickness on AAO showed best performance, among various deposition thicknesses. The resistances and Open Circuit Voltages were measured for various concentration combinations and maximum power was calculated. Experimental results show 10-2M-1M concentration combination has the maximum power performance.
