IEC 62282-3-100:2019

Fuel cell technologies - Part 3-100: Stationary fuel cell power systems - Safety

IEC 62282-3-100:2019 applies to stationary packaged, self-contained fuel cell power systems or fuel cell power systems comprised of factory matched packages of integrated systems which generate electricity through electrochemical reactions. This document is applicable to stationary fuel cell power systems intended for indoor and outdoor commercial, industrial and residential use in non-hazardous areas. This second edition cancels and replaces the first edition published in 2012. This edition includes the following significant technical changes with respect to the previous edition:
a) recognition that fuel carrying components qualified to leakage standards (soundness) need not be considered as potential flammable leak sources;
b) new annex for small power systems; and
c) clarifications for numerous requirements and tests

Technologies des piles à combustible - Partie 3-100: Systèmes à piles à combustible stationnaires - Sécurité

L’IEC 62282-3-100:2019 s’applique aux systèmes à piles à combustible autonomes assemblés pour être stationnaires ou aux systèmes à piles à combustible d’un ensemble assemblé en usine de systèmes intégrés qui génèrent de l’électricité par réactions électrochimiques. Le présent document s’applique aux systèmes à piles à combustibles stationnaires destinés à un usage à l'intérieur et à l'extérieur, commercial, industriel ou d'habitation, dans des zones non dangereuses. Cette deuxième édition annule et remplace la première édition parue en 2012. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) il n’est pas nécessaire de tenir compte des composants transportant le combustible qui sont qualifiés par rapport aux normes de fuite (intégrité) comme des sources potentielles de fuites inflammables;
b) nouvelle annexe relative aux petits systèmes à piles à combustible; et
c) éclaircissements relatifs à de nombreux essais et exigences.
