LIN Xiaomin(林晓敏)1,*,LüQiuyue(吕秋月)1,ZHU Lili(朱丽丽)1,LIU Xiaomei(刘晓梅)2Solid oxide fuel cell(SOFC)is regarded as a greenelectrochemical conversion device because of its re-markable advantages such as high generating efficiency,low emission and versatile fuel adaptability.However,SOFC that operates at high temperature(~1000 oC)shows many drawbacks,such as undesired reactions be-tween electrolytes and electrode interface,inadequatethermo mechanical compatibility due to mismatchedmaterial thermal expansion coefficients,electrode sinter-ing,shortening of battery life,and waste of thermal en-ergy.Therefore,the key for commercialization of SOFCis to enable cell operation within the intermedi-ate-temperature range of 600–800 oC,which mo...
