摘　　要：通过实验数据对生物质气固体氧化物燃料电池(BIO-SOFC)和生物质气内燃机两种不同的低热值生物质气发电系统的特点进行了研究,结果表明以生物质气为固体氧化物燃料电池(SOFC)的燃料时,生物质气的成分变化对SOFC性能的影响较大,而燃料热值对其发电性能影响很小。对于生物质内燃发电机组,燃料的热值对系统性能有较大的影响。通过实验详细分析了生物质气中各气体成分对固体氧化物燃料电池性能的影响。综合实验数据的对比及两种发电系统各自的特点,分析了两种生物质气发电方式的在不同应用领域的前景。The characteristics of two different types of power generation systems fueled low heat value biogas,namely biogas solid oxide fuel cell（BIO-SOFC） and biogas internal combustion engine,were studied according to the experimental data.The results showed that the composition of the biogas had obvious effect on the SOFC performance,while the fuel heat value did little effect on the power generation performance.For the power generation unit with the biogas internal combustion engine there was a bigger influence of the fuel heat value on the system performance.The influence of the biogas compositions on the SOFC performance was analyzed in detail according to the experimental data.The prospect of the two biogas power generation methods in various application fields was analyzed through the integration of the experimental data and the characteristics of the two power generation systems.biogas;solid oxide fuel cell;biogas power generation system
