| 摘 要： | 燃料电池系统的最大电效率（ηemax）对理解和发展燃料电池技术至关重要.本文通过对燃料电池系统的热力学分析，在考虑加热燃料与空气至燃料电池工作温度的热量需求的基础上，建立了燃料电池运行过程的能量平衡关系，进而推导出了ηemax的显式理论表达式.结果表明，与卡诺效率不同，ηemax与燃料有关.由于除氢燃料外，计算ηemax需要进行化学平衡计算，本文推导了烷烃燃料化学平衡态的解析解.所得理论模型被用于分析温度（T）与燃料水含量及废热回收率对ηemax的影响.结果表明，甲烷和丙烷燃料的ηemax随温度的升高而显著降低.此外，对中等废热回收率且运行于700 ℃≤T≤900 ℃的燃料电池系统，氢气燃料的ηemax要高于甲烷和丙烷燃料的ηemax.
