Experimental Platform for Research on High Temperature PEM Fuel Cells

实验是研究高温质子交换膜燃料电池(HT-PEMFC)的最直接、有效的手段之一。该文基于LabView软件,研发了一个用于高温PEM燃料电池研究的实验平台,用于采集温度、压强、质量流量,以及气体化学计量数等有价值的数据。该平台设置了质量流量、时间、步长等参数的控制策略,这些策略对于高温PEM燃料电池的车用化是必要的。应用该平台,测量了高温PEM单片燃料电池及1kW燃料电池堆的极化曲线和电压损失,完成了不同的流量控制策略下的对比实验,以便改善高温质子交换膜燃料电池在稳态和动态过程中的性能。这些研究结果有助于进一步研究高温质子交换膜燃料电池。

Experiments are one of the most direct and effective methods for research on high temperature proton exchange membrane fuel cell （HT-PEMFC）. An experimental platform was developed based on LabView for HT-PEMFC to acquire experimental data of valuable parameters such as the temperature, pressure, mass flow rate, and gas stoichiometry. The platform has control strategies for the parameters of the mass flow rate, time and step length, which are significant for the use of PEMFC vehicles. By using the platform, polarization curves and voltage losses were measured for both one-piece HT-PEMFCs and 1 kW HT-PEMFC stacks, while contrast experiments were completed using different mass flow rate control strategies to improve the performances of HT-PEMFC in the steady or dynamic process. The results are significant for further research on HT-PEMFCs.
