Technical Committee 9 – Electrical Equipment and Systems for Railway
Organization	International Electrotechnical Commission TC9 / TC105
Identification	IEC 63341-1 Railway applications – Rolling stock – Fuel cell systems for propulsion -Part 1: Fuel cell power system
Scope	This document applies to Fuel Cell System for traction and auxiliaries purpose used on rolling stock. This document applies to any rolling stock types (e.g. light rail vehicles, tramways, streetcars, metros, commuter trains, regional trains, high speed trains, locomotives, etc). This document focuses on: – the scope of supply and the description of the interfaces (fluidic, electrical and mechanical), – the description of environmental conditions, – the design requirements and the functional requirements to ensure the fuel cell system compliancy with a railway application – the definition of the standardization process to validate the fuel cell system capacity required for a specific mission profile, – the safety and protection requirement to design and install a fuel cell system for railway application, – the protection of persons and the environment inside and outside the vehicle against hydrogen related hazards – the marking and labelling requirements – the requirements related to storage, transportation, installation and maintenance – the tests (type and routine) to validate the fuel cell system.
Status	Initiated 2020.

Identification	IEC 63341-2 Railway applications – Rolling stock – Fuel cell systems for propulsion -Part 2: Hydrogen storage system
Scope	This document applies to Compressed Hydrogen Storage Systems (CHSS) installed onboard rolling stock for railway applications and 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, being the technology currently used for land transport vehicles. Therefore, liquid hydrogen storage systems are not treated in the present revision of the standard. This document applies to any rolling stock types (e.g. light rail vehicles, tramways, streetcars, metros, commuter trains, regional trains, high speed trains, locomotives, etc.). This standard addresses also the mechanical, fluidic and electrical interfaces between On-board Compressed Hydrogen Storage System and Refilling Station. Nevertheless, this standard does not specify Refilling Station itself nor the Refuelling Protocol, that are specified in other standards such as ISO 19880-1 or future one for Railway applications
Status	Initiated 2021.
