【摘要】：本文通過擠出成型法,成功制備了管式固體氧化物烘焙電池陽極支撐體,并以YSZ為電解質(zhì),LSM為陰極組裝成電池測(cè)試其電化學(xué)性能。為了改善陽極的結(jié)構(gòu),在陽極粉料分別中添加了三種造孔劑:石墨、玉米粉和淀粉,并進(jìn)行了單電池的組裝及電池性能測(cè)試。SEM分析和電化學(xué)測(cè)試結(jié)果都表明,與玉米粉和淀粉相比,石墨為造孔劑效果更好。另外,為了進(jìn)一步優(yōu)化陽極的性能,本文在以石墨為造孔劑時(shí),同時(shí)在陽極中添加了相當(dāng)于5%mol Ni的Fe離子。SEM結(jié)果顯示Fe離子的加入能夠減少陽極的燒結(jié),優(yōu)化陽極結(jié)構(gòu)。隨后的電化學(xué)性能測(cè)試亦表明,隨著Fe離子的加入,單電池的性能從241m W·cm~(-2)提高到了400m W·cm~(-2)。而由于Fe的電阻大于Ni,電池的歐姆阻抗與未添加Fe離子時(shí)相比有了一定的提高。
[Abstract]:In this paper, the anode support of tubular solid oxide baking battery was successfully prepared by extrusion molding, and YSZ was used as electrolyte. In order to improve the structure of the anode, three kinds of pore-making agents were added to the anode powder: graphite, corn powder and starch. The results of single cell assembly, battery performance test. SEM and electrochemical test show that graphite is better than cornmeal and starch. In addition, graphite is better than cornflour and starch. In order to further optimize the performance of the anode, graphite was used as the pore-forming agent in this paper. At the same time, the addition of Fe ion, equivalent to 5mol Ni, in the anode. SEM results show that the addition of Fe ion can reduce the sintering of anode. The subsequent electrochemical performance tests also showed that with the addition of Fe ions, the structure of the anode was optimized. The performance of single cell is improved from 241m W 路cm ~ (-2) to 400 MW 路cm ~ (-2). However, the resistance of Fe is greater than that of Ni. The ohmic impedance of the battery is higher than that without Fe ion.
