碩士 === 國立清華大學 === 材料科學工程學系 === 98 === This study investigated the influence of conducting polymer polyaniline on the electric properties of the porous aluminum paste electrode. After the filling treatment, the aluminum particles of the porous aluminum paste electrode were covered by a thin layer of PAni. The formation of composite electrode structure leads to increase of electric conductivity of electrode, cell efficiency, and endurance level of the cell were investigated in depth. In the PAni synthesis experiment, the effects of the dispersant and the doping acid on the thermal stability and the conductivity of the products were studied. In the electric conductivity, the effects of PAni coating on the conductivity of the composite electrode can be explained by the electron transport mechanism. In the cell efficiency experiment, the effects of the presence of the PAni coating layers on the cell efficiency were attributed to the series and shunt resistance. In the endurance experiment, the hydrothermal and the corrosion tests were adopted to study the anti-oxidative and the anti-corrosive capacities individually. Based on this study, the conductivity of the electrode was enhanced which is attributed to both the improvement of the electric properties of PAni and the formation of the composite electrode structure. Thus the cell efficiency and the endurance level were improved, and the highest increment of the cell efficiency in this study was 0.66 %.
