气体分析.氢燃料的分析方法.道路车辆用质子交换膜（PEM）燃料电池应用

[中文适用范围]： 本文件规定了用于确保使用质子交换膜（PEM）燃料电池的道路车辆的氢分配基地和加氢站的气态氢（H2）质量的分析方法的验证协议。 它还提供了有关金额分数的不确定性预算计算的建议。 本文件主要针对氢气配送基地或加氢站氢气采样后在实验室进行的分析而制定。 本文件未涉及在线监测的具体要求。 根据 ISO 14687 定义的 D 级氢规范，本文件列出了用于测量氢中每种杂质的合适分析技术： ——1)。 此外，还给出了保持样品完整性的建议，以确保测量质量。 它还包括报告分析结果的要求。 [外文原描述]： This document specifies the validation protocol of analytical methods used for ensuring the quality of the gaseous hydrogen (H 2 ) at hydrogen distribution bases and hydrogen fuelling stations for road vehicles using proton exchange membrane (PEM) fuel cells. It also gives recommendations on the calculation of an uncertainty budget for the amount fraction. This document is established mainly for analysis done in laboratories after the sampling of hydrogen either at hydrogen distribution bases or at hydrogen refuelling stations. The specific requirements for on-line monitoring are not covered by this document. This document gives a list of suitable analytical techniques used to measure each impurity in hydrogen, according to the specification of hydrogen grade D defined by ISO 14687:—[1]. Moreover, recommendations for keeping the integrity of the sample are also given in order to ensure the quality of the measurement. It also includes the requirements for reporting the analytical results. [1] Under preparation. Stage at the time of publication: ISO/DIS 14687:2018.
