中文摘要:
      为了提高电池开路电压校准效果,引入质子交换膜设计了一种电池开路电压校准方法。研究了新的质子交换膜燃料电池开路电压校准方法,通过分析质子交换膜燃料电池工作原理,以Nernst方程表示了质子交换膜燃料电池开路电压。在校准开路电压过程中,校准装置连接至测量点,质子交换膜燃料电池片放置在分选机上,通过采用分选机的I-V测量仪与校准装置同时测量质子交换膜燃料电池开路电压,对比了两组不测量数据;获取校准系数后,依照质子交换膜燃料电池开路电压的影响因素,分析了引入模拟器辐照度偏差、温度控制偏差和测量仪器重复性后开路电压校准不确定度。实验证明,方法平均校准误差值低于对比校准方法50%以上,且平均校准时间也比对比校准方法平均低1.77 s,说明该方法可实现高精度、高效率的质子交换膜燃料电池开路电压校准。
英文摘要:
      To improve the calibration effect on battery open-circuit voltage, a proton exchange membrane is intro-duced in this paper to design a battery open-circuit voltage calibration method. A novel open-circuit voltage calibration method for proton exchange membrane fuel cell(PEMFC) is studied. Its working principle is analyzed, and its opencirc-uit voltage is expressed by the Nernst equation. During the calibration process, a calibration device is connected to the measurement point. The PEMFC sheet is placed on the separator, and the open-circuit voltage is measured by an I-V meter in the separator and the calibration device simultaneously. Based on the comparison of two groups of non-measurement data, the calibration coefficient is obtained. According to factors affecting the open-circuit voltage of PEMFC, the uncertainties in the calibration due to the introduction of irradiance deviation in the simulator, temperature control deviation, and repeatability of measurement instruments are analyzed. Experimental results show that compared with the contrast method, the average calibration error of the proposed method was more than 50% lower and the corresponding average calibration time was 1.77 s shorter, indicating that it can achieve high-precision and high-efficiency PEMFC open-circuit voltage calibration.
