Study of Assembly Techniques for a Solid Oxide Fuel Cell Stack

固態氧化物燃料電池電池堆組技術之研究

摘要


固體氧化物燃料電池(Solid Oxide Fuel Cell,SOFC)是一種高溫操作的全固態的能量轉換裝置,具有效率高、燃料適應性強等優點。本文針對電池堆的密封材料,以A12O3-SiO2系統氧化物成功開發出適合平板式SOFC在800℃使用的密封材料。該材料在800℃與YSZ電解質和金屬雙極板有較好的浸潤黏附性能,尺寸穩定和絕緣性佳。建立單電池發電實驗裝置,實驗研究包括燃料組成、燃料濃度、溫度等操作條件對電池發電性能的影響,在700℃~750℃範圍內電池功率密度與溫度之間呈線性關係,濃度與流量對於發電性能有顯著影響,當氫氣濃度達100%時,發電性能最為優越;當氫氣流量達1200c.c./min時,最大功率可達340mW/平方公分。

Solid oxide fuel cell is an energy conversion device operated at high temperatures with the merits of high efficiency and good fuel adaptability. In our study, appropriate borosilicate glass-ceramics has successfully developed at INER for planar SOFC. A one-cell stack is assembled to evaluate the effects of fuel/oxidant gas flow rates, fuel concentration, and temperatures. The results indicate the cell power density increases linearly with temperature in the range of 700℃~750℃. Power output is highest at 100% hydrogen concentration. The power density reaches to 340mW/cm^2 as the low rate of hydrogen at 1,200c.c./min.
