IEC 62282-6-106:2024

Fuel cell technologies - Part 6-106: Micro fuel cell power systems - Safety - Indirect Class 8 (corrosive) compounds

IEC 62282-6-106:2024 covers micro fuel cell power systems, micro fuel cell power units and fuel cartridges using hydrogen produced from UN Class 8 (corrosive) borohydride formulations as fuel. These systems and units use proton exchange membrane (PEM) fuel cell technologies. The designs include fuel processing subsystems to derive hydrogen gas from the corrosive fuel formulation.
This first edition, together with the other parts of the IEC 62282-6-1XX series, cancels and replaces IEC 62282-6-100:2010 and IEC 62282-6-100:2010/AMD1:2012.This edition includes the following significant technical changes with respect to IEC 62282‑6‑100:2010 and IEC 62282-6-100:2010/AMD1:2012:
a) A new structure has been set up: IEC 62282-6-101 covers the general safety requirements common to all fuel types whereas IEC 62282-6-102 and subsequent parts of the IEC 62282-6-1XX series cover particular requirements for individual fuel types.

Technologies des piles à combustible - Partie 6-106: Systèmes à micropiles à combustible - Sécurité - Composés (corrosifs) indirects de classe 8

IEC 62282-6-106:2024 raite des systèmes à micropiles à combustible, des blocs d’alimentation électrique des micropiles à combustible et des cartouches de combustible qui utilisent comme combustible l’hydrogène produit à partir de formulations de borohydrure de classe 8 des Nations Unies (corrosifs). Ces systèmes et blocs d’alimentation utilisent des technologies de piles à combustible à membrane à échange de protons (PEM, Proton Exchange Membrane). Les conceptions incluent des sous-systèmes de traitement de combustibles pour obtenir un gaz hydrogène à partir de la formulation corrosive d’un combustible.
Cette première édition, ainsi que les autres parties de la série IEC 62282-6-1XX, annulent et remplacent l'IEC 62282-6-100:2010 et l'IEC 62282-6-100:2010/AMD1:2012. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’IEC 62282‑6‑100:2010 et l’IEC 62282-6-100:2010/AMD1:2012:
a) une nouvelle structure a été établie: l’IEC 62282-6-101 couvre les exigences générales de sécurité communes à tous les types de combustibles, tandis que l’IEC 62282-6-102 et les parties suivantes de la série IEC 62282-6-1XX couvrent les exigences particulières pour les différents types de combustibles.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch.
