| 摘 要： | 固体氧化物燃料电池是一种有前途的分布式电源。从基本的热力学分析出发并结合质量平衡、焓平衡和熵平衡方程,该文提出一个以氢气为燃料的固体氧化物燃料电池数学模型用于静态分析。推导得出了氢气利用系数、电池堆温度和过量氧气比例这3个运行变量之间的解析关系。由于固体氧化物燃料电池在运行中必须满足多个限制,该文提出了合理运行空间的概念。该概念可以用于指导固体氧化物燃料电池的运行和控制。

| Abstract: | Solid oxide fuel cell(SOFC) distributed generator(DG) is a promising DG technology.Starting from the fundamental thermodynamic analysis,a mathematical model governing the steady-state operating state of the hydrogen-fed SOFC was provided by including the mass balance,enthalpy balance and entropy balance equations.An analytical expression relating the SOFC performance variables such as fuel utilization factor,cell stack temperature and excess oxygen ratio were then derived.As the SOFC must be subject to some... |
