Abstract

Abstract: The equilibrium species and theoretical electromotive force of cells fed with NH₃ and 3% H₂O humidified H₂,CH₄,C₃H₈ and underground coal gasification(UCG)gas on the basis of minimum Gibbs free energy were calculated,whilst the open circuit voltage(OCV),V-I characteristics and long-term stability of NiO-GDC‖GDC‖Ba_0.9Co_0.7Fe_0.2Nb_0.1O_3-δ(B_0.9CFN)anode-supported cells operated in above five fuels were evaluated.The results showed that direct utilization of hydrocarbon fuels in anode could achieve a desirable electromotive force (EMF)no less than 1.05 V,while the OCV for ceria-based cells was comparatively poorer due to the presence of electronic conductivity.Besides,the synergy effect between stagnant kinetics of hydrocarbons reforming and the relatively sufficient O^2- supply due to fast migration of oxide ions suppressed carbon deposition at low operating temperatures for ceria-based SOFC. Furthermore,the UCG gas fed cell exhibited peak power densities as high as 0.151,0.299,0.537 and 0.729 W·cm^-2,respectively at 500,550,600 and 650℃,and showed no evident performance decay and carbon deposition on anode after discharging at 600℃ under a constant voltage of 0.6 V for 120 h,thereby demonstrating UCG gas is a promising fuel for direct utilization in SOFC.

Key words: solid oxide fuel cell, UCG gas, thermodynamic equilibrium, electromotive force, carbon deposition

摘要： 以NH₃以及3% H₂O增湿的H₂、CH₄、C₃H₈和煤炭地下气化(underground coal gasification,UCG)气为燃料,用最小Gibbs自由能法计算平衡气体组分和理论电池电动势,并测试在NiO-GDC‖GDC‖Ba_0.9Co_0.7Fe_0.2Nb_0.1O_3-δ(B_0.9CFN)阳极支撑固体氧化物燃料电池(SOFC)中的电池开路电压、电池性能和长期稳定性。结果表明,以上述气体作燃料的SOFC热力学计算理论电动势均高于1.05 V,而由于GDC电解质在还原气氛下存在电子电导,导致碳氢燃料在NiO-GDC‖GDC‖B_0.9CFN阳极支撑电池中的开路电压略小。中低温下,碳氢燃料相对缓慢的动力学过程和GDC电解质快速的氧离子传输速率,使得以UCG气、CH₄和C₃H₈为燃料的电池实际积炭比理论预测少。以UCG气为燃料的SOFC在500、550、600和650℃的最高功率密度分别高达0.151、0.299、0.537和0.729 W·cm^-2,在0.6 V恒压放电120 h后性能没有明显衰减,且阳极表面无积炭产生,表明直接UCG气SOFC具有广阔的应用前景。
