在燃料电池阳极系统中，阳极循环系统将燃料电池阳极出口未反应的氢气再次循环到燃料电池堆的氢气入口，通过这种方式可以提高氢气利用率，改善燃料电池堆的湿度，减少氮气累积的影响。为了提高系统整体效率，越来越多的阳极循环系统引入引射器作为关键零部件。本文建立了燃料电池氢循环泵和引射器并联的阳极循环系统仿真模型。针对300 kW燃料电池系统的运行工况，分析了零部件关键参数对系统的影响，并对阳极循环系统在燃料电池系统全工况范围下的运行状态进行了计算。本模型可以支持不同氢气系统架构的仿真计算，为燃料电池系统架构的设计提供依据。
Abstract：In the fuel cell anode system, the hydrogen recirculation system recycles unreacted hydrogen from the fuel cell anode outlet to the inlet. This approach enhances hydrogen utilization efficiency, improves the humidity of the stack, and reduces nitrogen accumulation. To improve system efficiency, the ejector is adopted as a critical component in current anode recirculation systems. This study establishes a simulation model for a fuel cell anode recirculation system employing a parallel configuration of hydrogen circulation pump and ejector. Focusing on the operational conditions of a 300 kW fuel cell system, the research analyzes the influence of key component parameters. Additionally, it calculates the operational states of the anode recirculation system across the full operating range of the fuel cell system. This model can support the simulation calculations of different hydrogen system configurations, providing a basis for the design of fuel cell system architectures.
