| 摘 要： | 采用柠檬酸-硝酸盐燃烧法合成了Y和Nd共掺杂的铈酸钡BaCe0.8Y0.15Nd0.05O3-δ(BCYN)质子导体,并将其与多孔Pt电极组装了乙烷制乙烯共发电固体氧化物燃料电池(SOFC)。多孔Pt电极对乙烷脱氢和氧还原均具有很好的催化活性。BCYN质子陶瓷电解质膜则能够将阳极的碳氢化合物气体与阴极的氧隔开,从而避免乙烷的深度氧化而排放出CO2温室气体并且提高乙烯产物的选择性。在650℃时,电池的最大功率密度为146 mW/cm2,乙烷的转化率为18.6%,选择性为96.7%,主要副产物为甲烷。 |
| 关 键 词： | 固体氧化物燃料电池 质子导体 乙烷脱氢 二氧化碳 乙烯 |

| Abstract: | Y and Nd co-doped barium cerate(BCYN) proton conductor was synthesized by citric-nitrate combustion method.Solid oxide fuel cells(SOFCs) were fabricated using porous Pt electrodes and BCYN membrane electrolyte for co-generation of electricity and ethylene from ethane.Porous Pt electrodes had good catalytic activity toward to ethane dehydrogenation and oxygen reduction.BCYN proton conducting membrane could separate hydrocarbon in anode chamber and oxygen in cathode chamber thus could avoid ethane deep oxidation to CO2 emission and improve the ethylene selectivity.At 650 ℃,the maximum power density was 146 mW/cm2,the ethane conversion was 18.6%,the ethylene selectivity was 96.7%,and the main by-production was methane. |
| Keywords: | solid oxide fuel cell proton conductor ethane dehydrogenation carbon dioxide ethylene |
