摘要:

为了在温带、寒带地区推广燃料电池汽车,研究了含20片单体电池、活性面积为285 cm2的石墨基双极板聚合物电解质燃料电池短堆的零下启动。开发了基于实车的使用交互氢泵的电源系统;对短堆阳极和阴极同时供应氢气;用低温环境舱来构建-30 ℃环境;以起始膜—水(分子数)含量、交互电幅值及频率等作为3个控制参数,实现燃料电池短堆-30 ℃启动;测试了短堆零下启动前后的极化曲线。结果表明:燃料电池短堆-30 ℃启动后,中心位置的单体电池可在80 s内温升至0 ℃;在其余位置,可在200 s内温升至0 ℃;零下启动前后的极化性能基本无衰减。

Abstract:

Starting a fuel cell vehicle (FEV) under sub-zero temperature is one of the main obstacles to popularize FEVs in temperate and cold regions. This paper investigated the sub-zero start-up for a short stack of graphite-based bipolar plate polymer electrolyte fuel cells (PEFC) with 20 single cells and an active area of 285 cm2. Developed a power supply system by using an alternate hydrogen pump based on a real vehicle, with supplying hydrogen to the anode and the cathode of a short stack at the same time in a low-temperature environment chamber to create a -30 °C start-up environment. The initial molecule-number content of membrane to water, the alternating electric amplitude and the frequency were three control parameters to achieve the -30°C start-up of the PEFC short stack. The polarization curves of the short stack were tested before and after the sub-zero start-up. The results show that the single cell reaches 0 °C in 80 s in the middle of a short PEFC stack, and rises to 0 °C in 200 s in the other places of the stack. There is basically no polarization attenuation in the stack before and after the sub-zero start-up.

Key words: fuel cell vehicles (FEVs), polymer electrolyte fuel cell (PEFC), graphite-based bipolar plate stack, alternate hydrogen pump method, sub-zero start-up
