Fuel cell technologies - Part 2-100: Fuel cell modules - Safety (IEC 62282-2-100:2020)

This part of IEC 62282 provides safety related requirements for construction, operation under
normal and abnormal conditions and the testing of fuel cell modules. It applies to fuel cell
modules with the following electrolyte chemistry:
• alkaline;
• polymer electrolyte (including direct methanol fuel cells)2;
• phosphoric acid;
• molten carbonate;
• solid oxide;
• aqueous solution of salts.
Fuel cell modules can be provided with or without an enclosure and can be operated at
significant pressurization levels or close to ambient pressure.
This document deals with conditions that can yield hazards to persons and cause damage
outside the fuel cell modules. Protection against damage inside the fuel cell modules is not
addressed in this document, provided it does not lead to hazards outside the module.
These requirements can be superseded by other standards for equipment containing fuel cell
modules as required for particular applications.
This document does not cover fuel cell road vehicle applications.
This document is not intended to limit or inhibit technological advancement. An appliance
employing materials or having forms of construction differing from those detailed in the
requirements of this document can be examined and tested according to the purpose of these
requirements and, if found to be substantially equivalent, can be considered to comply with
this document.
The fuel cell modules are components of final products. These products require evaluation
according to appropriate end-product safety requirements.
This document covers only up to the DC output of the fuel cell module.
This document does not apply to peripheral devices as illustrated in Figure 1.
This document does not cover the storage and delivery of fuel and oxidant to the fuel cell
module.

l’IEC 62282-2-100:2020 fournit des exigences relatives à la sécurité concernant la construction, le fonctionnement dans des conditions normales et anormales, et l’essai des modules à piles à combustible. Le présent document couvre les conditions qui peuvent générer des dangers pour les personnes et des dommages à l'extérieur des modules à piles à combustible. La protection contre les dommages affectant l'intérieur des modules à piles à combustible n'est pas traitée dans le présent document, à condition que ceux-ci ne suscitent pas de dangers à l'extérieur du module. Ces exigences peuvent être remplacées par d'autres normes applicables aux équipements contenant des modules à piles à combustible comme l’exigent les applications spécifiques. Cette première édition annule et remplace l’IEC 62282-2 parue en 2012. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’IEC 62282-2:2012: • mise à jour des définitions, notamment celle du module à pile à combustible pour fonctionnement normal; • traitement des valeurs de fuite en fonctionnement normal et anormal; • introduction d’un essai d'allumage retardé; • introduction de mesures de protection destinées à limiter les fuites de gaz; • mise à jour des exigences d’isolation entre les parties actives et la TBTS; • la stratégie générale de sécurité a été modifiée afin de prendre en compte les besoins concernant différentes normes d’application; ces modifications s’alignent sur les modifications similaires effectuées au niveau de l’IEC 62282-3-100; • l’article relatif aux composants électriques a été modifié afin de prendre en compte les besoins concernant différentes normes d’application; ces modifications s’alignent sur les modifications similaires effectuées au niveau de l’IEC 62282-3-100; • installation d’une mise à la terre de protection comme partie intégrante du module ou d’une liaison comme mesure interne à l’installation; • mise à jour exhaustive de l’essai de rigidité diélectrique par référence à l’IEC 62744-1 pour les tensions jusqu’à 1 000 V en courant alternatif/1 500 V en courant continu; • introduction d'une nouvelle méthode d’essai de fuite par "chute de pression" • une nouvelle Annexe relative aux dangers, situations et événements dangereux traités dans le présent document et associée à 4.1 (Stratégie de sécurité générale) a été ajoutée.

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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62282-2-100 has been prepared by IEC technical committee 105:

Fuel cell technologies.
This first edition cancels and replaces IEC 62282-2, published in 2012.

This edition includes the following significant technical changes with respect to

IEC 62282-2:2012:
• references to IEC 60050-485 instead of IEC TS 62282-1;
• update of normative references;
• update of definitions, in particular fuel cell module for normal operation;
• leakage values under normal and abnormal operation have been addressed;
• a delayed ignition test has been included;

FUEL CELL TECHNOLOGIES –
Part 2-100: Fuel cell modules – Safety
1 Scope

This part of IEC 62282 provides safety related requirements for construction, operation under

normal and abnormal conditions and the testing of fuel cell modules. It applies to fuel cell

modules with the following electrolyte chemistry:
• alkaline;
• polymer electrolyte (including direct methanol fuel cells) ;
• phosphoric acid;
• molten carbonate;
• solid oxide;
• aqueous solution of salts.

Fuel cell modules can be provided with or without an enclosure and can be operated at

significant pressurization levels or close to ambient pressure.

This document deals with conditions that can yield hazards to persons and cause damage

outside the fuel cell modules. Protection against damage inside the fuel cell modules is not

addressed in this document, provided it does not lead to hazards outside the module.

These requirements can be superseded by other standards for equipment containing fuel cell
