轨道交通应用 轨道车辆氢能和燃料电池系统 第2部分：氢燃料系统

[中文适用范围]： IEC 63341-2:2025适用于用于铁路车辆（如IEC 62864-1中定义的混合动力车辆）牵引动力和辅助供电的车载氢燃料系统（HFS）。本文件适用于以气态形式储存氢气的情况，不涵盖其他储存方式（如液态、液态低温压缩、金属氢化物等）。本文件适用于各种类型的轨道交通车辆（如轻轨车辆、有轨电车、市郊铁路、地铁、通勤列车、区域列车、高速列车和机车）。本文件涉及车载氢燃料系统与加氢站之间的机械、流体和电气接口。加氢站、加氢协议及相关的通信不在本文件的范围内。本文件规定了以下内容：氢燃料系统的供应范围及与轨道车辆内部和外部子系统（如燃料电池动力系统和加氢站系统）接口的描述；环境约束条件；支持HFS适用于铁路应用的设计要求；用于铁路应用的HFS设计和安装的安全性和可靠性要求；标识和标签要求；与储存、运输、安装和维护相关的各项要求；以及验证（包括型式试验、常规试验和调查试验）要求。 [外文原描述]： IEC 63341-2:2025 applies to on-board hydrogen fuel systems (HFSs) used to supply the fuel cells for the traction power and the auxiliaries supply of railway vehicles (such as hybrid vehicles as defined in IEC 62864-1). This document applies to hydrogen storage in gaseous form. Other means of storage (such as liquid, liquid cryo-compressed, metal hydrides) are not covered in this document. This document applies to any rolling stock type (e.g. light rail vehicles, tramways, streetcars, metros, commuter trains, regional trains, high speed trains, locomotives). This document addresses the on-board mechanical, fluidic and electrical interfaces between the on-board hydrogen fuel system and fuelling station. The fuelling station, fuelling protocol and communication for the fuelling protocol are not in the scope of this document. This document defines: – the scope of supply of hydrogen fuel system and the description of the interfaces with sub systems internal and external to the rolling stock such as fuel cell power system, fuelling station systems; – the environmental constraints; – the design requirements to support HFS compliance with railway applications; – the safety and reliability requirements to design and install the HFS for railway applications; – the marking and labelling requirements; – the requirements related to storage, transportation, installation and maintenance; – the validation (type, routine and investigation tests) requirements.
