固体氧化物燃料电池发电效率研究及应用前景展望

大部分传统发电系统,随着系统复杂性的提高,整体发电效率会下降。但固体氧化物燃料电池(SOFC)技术在由电堆扩展为全系统的过程中,发电效率可以提升。文章通过构建SOFC发电全系统的能量传送和转换模型,研究揭示了这一特殊规律,提出了ZK算法模型和ZK效率公式。该算法模型和效率公式可以精确计算出不同燃料对应的不同放大系数及全系统发电效率的上限,为SOFC发电系统的工程设计提供清晰的理论指导,并指明优化和改进的方向。

The Most traditional power generation systems, with the increase of system complexity, will reduce the overall power generation efficiency. However, the solid oxide fuel cell （SOFC） technology can increase power generation efficiency as it ex- pands from a stack to a full system. This paper constructs the energy transfer and conversion model of SOFC power generation system and studies reveals this special law. ZK algorithm model and ZK efficiency formula are proposed. The algorithm model and efficiency formula can accurately calculate the upper limit of the different amplification factors and the total system power generation efficiency for different fuels, provide clear theoretical guidance for the engineering design of SOFC power generation system, and indicate the direction of optimization and improvement. This effect is similar to the Camot cycle model and Carnot efficiency formula in the heat engine field.
