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. IEC shall not be
held responsible for identifying any or all such patent rights.
IEC TS 62282-7-1 has been prepared by IEC technical committee 105: Fuel cell technologies.
It is a Technical Specification.
This third edition cancels and replaces the second edition published in 2017. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the harmonization with the “EU Harmonised Test Protocols for PEMFC-MEA Testing in
Single Cell Configuration for Automotive Applications” published by Joint Research Centre
(JRC) of European Commission;
b) restructuring of the format: move the applied performance test methods in Annex H (Edition
2) to the main body and restructure the clause of testing and measurements;
c) add new example single cell designs to Annex A and Annex B.
The text of this Technical Specification is based on the following documents:
Draft Report on voting
105/1120/DTS 105/1138/RVDTS
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this Technical Specification is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
A list of all parts of the IEC 62282 series, published under the general title Fuel cell
technologies, can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
– reconfirmed,
– withdrawn, or
– revised.
INTRODUCTION
This part of IEC 62282 describes standard single-cell test methods for polymer electrolyte fuel
cells (PEFCs). This document has been mainly based on the research and development of
PEFCs [1], [2], [3], [4], [5], [6], [7], [8], [9], and provides consistent and repeatable methods to
test the performance of single cells. This document should be used by component
manufacturers or stack manufacturers who assemble components in order to evaluate the
performance of cell components, including membrane electrode assemblies (MEAs) and flow
plates. This document is also available for fuel suppliers to determine the maximum allowable
impurities in fuels.
Users of this document can selectively execute test items suitable for their purposes from those
described in this document. This document is not intended to exclude any other methods.
Although this document is for proton exchange membrane fuel cells (PEMFCs) as stated in the
scope, users can use this document as a reference to other types of electrolyte membrane fuel
cells because they have a certain similarity to PEMFC in test items and test methods.

1 Scope
This document covers cell assemblies, test station setup, measuring instruments and
measuring methods, performance test methods, and test reports for PEFC single cells.
This document is used for evaluating:
a) the performance and durability of membrane electrode assemblies (MEAs) for PEFCs in a
single cell configuration;
b) materials or structures of PEFCs in a single cell configuration; or,
c) the influence of impurities in fuel and/or in air on the fuel cell performance and durability.
This document is for proton exchange membrane fuel cells (PEMFC) basically having flow field
configurations and using hydrogen or hydrogen containing gas as fuel. It excludes from the
scope fuel cells based on anion exchange membranes, bipolar membranes, and phosphoric
acid doped polybenzimidazole membranes.
