针对目前常用的燃料电池氢气供应方式存在氢气利用率低、耗能大和使用范围小等缺点,本文中提出了基于MotoTron平台的氢共轨喷射系统快速原型开发技术。通过对控制参数的整定,达到共轨喷射系统氢气输出稳态误差合理、出口流量动态可调的目的。结果表明,该方法能使氢气在燃料电池阳极分布更为均匀,提高了氢气利用率,延长了燃料电池寿命,为后续的整车开发奠定了基础。

In view of the low utilization rate of hydrogen, high other defects of the way of hydrogen technique for common rail hydrogen supply commonly used in fuel cell energy consumption, narrow use scope and at present, a rapid prototyping development injection system is proposed based on MotoTron platform. By tuning the control parameters, reasonable steady-state error of hydrogen output and dynamically adjustable exit flow rate are realized. The results show that the technique proposed can enable evener distribution of hydrogen at fuel cell anode, raise the utilization rate of hydrogen and extend the lifespan of fuel cell, laying a foundation for subsequent vehicle development.
