摘要
工廠排放是二氧化硫的一個主要來源，在現今的工業處理方式中，需要添加大量的吸收劑去中和，耗費了大量的設備成本，並且會產生大量的二次汙染物，增加後端處理的難度，在空氣汙染日趨嚴重，各國政府對於廢氣排放標準更加嚴格之情況下，無疑會讓未來的成本負擔更加巨大。 實驗室所發展之電化學雙電池(Electrochemical double cell, EDC)，其利用陰極材料與陽極材料之間產生的電動勢(Electromotive force, EMF)使二氧化硫在觸媒表面上進行分解反應以達到減排的效果。 為更符合實際應用狀況，將EDC的面積放大，使用目前面積體積比最大之蜂巢狀陽極幾何結構來做為基材，可大量節省空間，降低成本時也可達到相同效果。 由於陽極蜂巢狀結構較為複雜，且電解質層塗佈為所有功能層中最重要之步驟，藉由各種塗佈方式以及漿料配比的嘗試，得出最接近商業化平板狀電池片電解質層之結果，以為未來陽極蜂巢的製作奠基。

Nowadays, the emission of factory is one of the source of SO2. In the normal way to deal with SO2, we need a lot of absorbent and neutralizer. The equipment cost is very large, and this way will produce many secondary pollutants which enhance the after treatment difficulty. As the air pollution is growing, the government emission standard becomes stricter and stricter. A company will need more cost in the future which taking bad influence for expenditure. We developed the electrochemical double cell (EDC) using the electromotive force (EMF) between cathode and anode material to promote the SO2 decomposition on the catalyst surface for reducing the emission of SO2. According to the real situation, the larger area is needed. Using the anode honeycomb which has the best area volume ratio to be the substrate. It can reduce the space to reach the same result. In the EDC production process, the electrolyte layer is most important step. The effectiveness depends on the densification of the electrolyte layer. However, basing on the complicate structure of honeycomb, we try different coating method and component ratio of coating solution to reach the effect of commercial cell plate’s electrolyte layer.
