离子色谱法测定燃料电池汽车用氢气中的甲酸杂质含量

Determination of Formic Acid Impurities in Hydrogen for Fuel Cell Vehicle by Ion Chromatography

氢燃料电池汽车行业发展如火如荼,车用氢燃料由于其较高的品质要求,越来越为业界所关注。其中的甲酸杂质,目前没有特别优势的检测方法和标准。根据甲酸水溶性特征,通过吸收气体中甲酸的方法,利用离子色谱进行检测,不仅可以达到燃料电池汽车用氢气的指标要求,还可以兼顾其他水溶性杂质的检测,属于气体中杂质检测方法的进步与创新。

The development of hydrogen fuel cell vehicle industry is in full swing.Because of its high quality requirements,the hydrogen fuel for vehicle is more and more concerned by the industry.At present,there are no special methods and standards for the determination of formic acid impurities.According to the water-soluble characteristics of formic acid,the method of absorption of formic acid in gas and detection by ion chromatography can not only meet the requirements of hydrogen for fuel cell vehicles,but also take into account the detection of other water-soluble impurities,which belongs to the progress and innovation of the detection method of impurities in gas.
