DANSK DSF/PREN IEC 63341-2 PDF

This document applies to hydrogen fuel systems (HFS) 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. NOTE – This document can also be used as informative recommendations for applications with hydrogen internal combustion engines. This document applies to hydrogen storage in gaseous form, being the primary technology currently used for land transport vehicles. Other means of storage (such as liquid, liquid cryo- compressed, metal hydrides), are not treated in the present revision of the standard. 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 mechanical, fluidic and electrical interfaces between the on-board hydrogen fuel system and refilling station. The refilling station, refuelling protocol and communication for the refuelling protocol are not in the scope of this document.
