Anotation

IEC 63341-3:2025 specifies the performance evaluation methodologies for fuel cell power systems that are designed for utilisation in electrically propelled rolling stock. The scope of this document concerns itself exclusively with electrically powered rolling stock. Internal combustion engines utilising hydrogen are not encompassed within the scope of this document. This document is applicable to hydrogen fuel cell power systems for electrically propelled rolling stock. This document does not apply to reformer-equipped fuel cell power systems. This document does not cover the hydrogen fuel systems that are permanently or separately attached to either the rolling stock or the fuel cell power system. These systems are addressed in IEC 63341-2. The fundamental system overview, incorporating the interrelationships between the primary functions and the connections to the external system, is delineated in IEC 63341-1:2025, Figure 4. The relevant standards are comprehensively delineated in IEC 63341-1. The performance targets for fuel cell power systems are agreed upon between the user and the manufacturer l’IEC 63341-3:2025 specifie les methodologies d’evaluation des performances applicables aux systemes a pile a combustible qui sont concus pour etre utilises sur du materiel roulant a propulsion electrique. Le domaine d’application du present document se limite exclusivement au materiel roulant a propulsion electrique. Les moteurs a combustion interne a hydrogene ne relevent pas du domaine d’application du present document. Le present document s’applique aux systemes a pile a combustible a hydrogene destines au materiel roulant a propulsion electrique. Le present document ne s’applique pas aux systemes a pile a combustible equipes d’un reformeur. Le present document ne couvre pas les systemes a hydrogene qui sont fixes de facon permanente, ou en tant qu’element distinct, au materiel roulant ou au systeme a pile a combustible. Ces systemes sont traites dans l’IEC 63341-2. La vue d’ensemble du systeme fondamental, comprenant les relations entre les fonctions principales et les connexions avec le systeme externe, est representee graphiquement a la Figure 4 de l’IEC 63341-1:2025. Les normes appropriees sont decrites de maniere exhaustive dans l’IEC 63341-1. Les objectifs de performance pour les systemes a pile a combustible font l’objet d’un accord entre l’utilisateur et le fabricant.
