在700 ~ 800℃的温度范围内，对各种生物燃料的内重整SOFC性能进行了评价。将3种真实的生物柴油燃料（bdf）和2种不饱和CC键含量不同的纯脂肪酸甲酯（FAMEs）直接添加到阳极负载sofc中。结果表明，将BDF直接加注到SOFC中原则上是可行的，但BDF中不饱和脂肪酸的含量应尽可能低。直接加注bdf引起的碳沉积在较低的操作温度和较高的不饱和脂肪酸含量下更为显著。另一方面，垃圾厌氧发酵产生的沼气含有天然转化剂（CO2），适合SOFC操作。通过向沼气中加入适量的空气，实现了沼气内转化SOFC的稳定运行。
Performance of internal reforming SOFC was evaluated in the temperature range of 700-800 o C for various biofuels. Three real biodiesel fuels (BDFs) and two pure fatty acid methyl esters (FAMEs) with different contents of unsaturated CC bonds were fed directly to anode-supported SOFCs. The results demonstrated that in principle direct-feeding of BDFs into SOFC is viable, but the content of unsaturated FAMEs in BDF should be as low as possible. Direct feeding of BDFs caused carbon deposition which was more significant at lower operational temperatures and at higher contents of unsaturated FAMEs. On the other hand, biogas obtained by anaerobic fermentation of garbage, is suitable for SOFC operation because it contains natural reforming agent (CO2). Stable operation of internal reforming SOFC running on biogas was achieved by the addition of adequate amount of air to biogas.
