标准摘要
[中文适用范围]： 该 TIR 的成果是建立质子交换膜 (PEM) 测试方法和 HRS 中使用的化学品的表征，这些化学品在运行和维护过程中可能会影响商用 PEM 燃料电池汽车的性能。 SAE J2719 等氢气质量标准提供了最大杂质含量的污染物清单，可确保燃料电池汽车的安全运行。这些污染物主要来自氢气生产。这些质量标准很少关注 HRS 安装、操作和维护过程中产生的污染物。 HRS运行期间使用的常见化学品是制冷剂、润滑剂等，HRS安装和维护期间使用的常见化学品是溶剂清洁剂、润滑剂等。其中一些化学品被发现对PEM燃料电池有不利影响。 [外文原描述]： The outcome of this TIR is to establish proton exchange membrane (PEM) testing methods and characterization of chemicals used in HRS, during operation and maintenance that can influence the performance of commercial PEM fuel cell vehicles.Hydrogen quality StandardDetails such as SAE J2719 provide list of contaminants with maximum impurity levels that ensure safe operation of fuel cell vehicles. These contaminants are primarily from the hydrogen production. Less attention in these quality StandardDetails were given to the contaminants generated from the installation, operation and maintenance of HRS. Common chemicals used during HRS operation are refrigerants, lubricants, etc., and during HRS installation and maintenance are solvents cleaning agents, lubricants, etc. Some of these chemicals are found to have adverse impacts on PEM fuel cells.The development of testing methods and characterization of chemicals in this report are based on similar methods used in SAE J2719 although the approach in this TIR is a direct evaluation of the chemical rather than specifying the contaminant level. These methods consider fuel cell performance characteristics for each chemical tested and the impacts of functional groups on PEM fuel cells. Adverse impact of contaminants on fuel cells are associated with performance drop after exposure to the chemical.Cross Reference:
