【摘要】：固體碳的CO_2氣化反應(yīng)(C+CO_2=2CO),即逆Boudouard反應(yīng),是制約固體氧化物直接碳燃料電池(solid oxide direct carbon fuel cell,SO-DCFC)性能的關(guān)鍵反應(yīng)之一。文章在比較煤焦和擔(dān)載酸活化鋼渣的煤焦的逆Boudouard反應(yīng)性的基礎(chǔ)上,研究比較了以二者為燃料的SO-DCFC的電化學(xué)性能。結(jié)果表明,酸活化鋼渣催化劑使煤焦的逆Boudouard反應(yīng)的起始溫度降低了240℃,在800℃時(shí)的CO生成速率提高了4倍;在電化學(xué)性能上,酸活化鋼渣催化劑使電池在850℃時(shí)的峰值功率密度從67.4mW·cm~(-2)提升到200.4mW·cm~(-2),燃料利用率從41.5%提高至79.6%。
[Abstract]:The CO_2 gasification reaction of solid carbon is one of the key reactions that restrict the solid oxide direct carbon fuel cell SO-DCFCs of solid oxide direct carbon fuel.On the basis of comparing the inverse Boudouard reactivity of char with acid-supported activated steel slag, the electrochemical properties of SO-DCFC based on them were studied and compared.The results show that the starting temperature of the inverse Boudouard reaction of char is reduced by 240 鈩，
