摘要
杂质含量过多的氢气会引起车用氢燃料电池阳极催化剂中毒,减少车用燃料电池的使用寿命。为准确而快速检测出氢气气体杂质的含量,以实现对氢气品质的有效评价,本文使用离子分子反应质谱仪对国内车用氢气品质进行测试。先使用标准样品气体对离子分子反应质谱仪进行校准,来检验离子分子反应质谱仪测试氢气杂质含量的准确性和稳定性。然后用该离子分子反应质谱仪对4种氢气样品进行测试,分析氢气样品的氢气品质。实验结果发现,离子分子反应质谱仪可以快速而准确地测试出氢气样品的杂质含量,4种氢气样品的优劣依次为样品1,样品4,样品3和样品2。
Hydrogen with too much impurity can poison anode catalyst of the vehicle hydrogen fuel cell,decreasing service life of the fuel cell for the vehicle.To accurately and quickly detect the gasimpurity content of hydrogen and achieve an effective evaluation of hydrogen quality,we use ionmolecular reaction mass spectrometer to test the quality of domestic vehicle hydrogen.The ionmolecular reaction mass spectrometer is first calibrated by using a standard sample gas to further verify its accuracy and stability of testing hydrogen impurity content.Then,four kinds of hydrogen samples are tested by the ion-molecular reaction mass spectrometer to analyze the gas quality of the hydrogen sample.The results show that the ion-molecular reaction mass spectrometer can quickly and accurately test the impurity content of the hydrogen sample.The sequence from high quality to inferior quality is sample 1,sample 4,sample 3 and sample 2,respectively.
