Ta del standarda IEC 62282 določa metode za vrednotenje tipičnega delovanja sistemov za shranjevanje električne energije, ki uporabljajo vodik. Uporablja se za sisteme, ki uporabljajo naprave za elektrokemično reakcijo tako za polnjenje kot praznjenje. Ta dokument se uporablja za sisteme, ki so zasnovani za servisiranje in delovanje na stacionarnih lokacijah (v zaprtem prostoru in na prostem) ter se uporabljajo za te namene.
Konceptualne konfiguracije sistemov za shranjevanje električne energije, ki uporabljajo vodik, so prikazane na slikah 1 in 2.
Slika 1 prikazuje sistem, ki je samostojno opremljen z modulom elektrolizatorja in modulom gorivne celice. Slika 2 prikazuje sistem, ki je opremljen z modulom reverzibilne celice.
Nujno potrebne komponente so modul elektrolizatorja in modul gorivne celice ali modul reverzibilne celice, celoten sistem za upravljanje (ki vključuje podatkovni vmesnik in lahko vključuje upravljanje tlaka), sistem za uravnavanje toplote (ki lahko vključuje enoto za shranjevanje toplote), sistem za upravljanje z vodo (ki lahko vključuje enoto za shranjevanje vode) in dovod prepihovalnega plina (inertni plin, ki ne oksidira in se ne reducira).
OPOMBA 1: Nujno potrebne komponente so na slikah 1 in 2 označene s krepko polno črto.
Sistem lahko vključuje enoto za shranjevanje vodika ali povezavo z zunanjo infrastrukturo za dovod vodika oziroma kombinacijo obojega. Izbirni komponenti sta lahko baterija in enota za shranjevanje kisika.
Modul elektrolizatorja lahko vključuje enega ali več elektrolizatorjev enakega ali različnega tipa. Glede na delovne pogoje in ob upoštevanju preteklega delovanja lahko celoten sistem za upravljanje nadzoruje sočasno delovanje elektrolizatorjev. Modul gorivne celice lahko vključuje eno ali več gorivnih celic enakega ali različnega tipa. Glede na delovne pogoje in ob upoštevanju preteklega delovanja lahko celoten sistem za upravljanje nadzoruje sočasno delovanje gorivnih celic. Modul reverzibilne celice lahko vključuje eno ali več reverzibilnih celic enakega ali različnega tipa. Modul gorivne celice lahko vključuje eno ali več gorivnih celic enakega ali različnega tipa. Glede na delovne pogoje in ob upoštevanju preteklega delovanja lahko celoten sistem za upravljanje nadzoruje sočasno delovanje reverzibilnih celic.
Merjenje učinkovitosti delovanja se izvaja v opredeljenem območju, obdanem s krepko zunanjo polno črto (meja sistema).
OPOMBA 2: Izraz »»reverzibilen« se v tem dokumentu ne navezuje na termodinamični pomen idealnega procesa. Na področju gorivnih celic je običajno, da se način delovanja celice, ki izmenično
deluje v načinu gorivne celice in načinu elektrolizatorja, imenuje »reverzibilen«.
Ta dokument je namenjen izmenjavi podatkov pri komercialnih transakcijah med proizvajalcem sistema in stranko. Uporabniki tega dokumenta lahko izvajajo preskusne elemente, opisane v tem dokumentu, ki so primerni za njihov namen.

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.

INTRODUCTION
This part of IEC 62282 specifies performance evaluation methods for electric energy storage
systems using hydrogen that employ electrochemical reactions both for water and steam
electrolysis and electric power generation.
NOTE Heat generation can be a secondary purpose.
This document is intended for power-to-power systems which typically employ a set of
electrolyser and fuel cell, or a reversible cell for devices of electric charge and discharge.
A typical target application of the electric energy storage systems using hydrogen is in the class
of energy intensive electric energy storage. The systems are recognized as critically useful for
the relatively long-term power storage operation, such as efficient storage and supply of the
renewable power derived electric energy and grid stabilization.
The IEC 62282-8 series aims to develop performance test methods for power storage and
buffering systems based on electrochemical modules (combining electrolysis and fuel cells, in
particular reversible cells), taking into consideration both options of re-electrification and
substance (and heat) production for sustainable integration of renewable energy sources.
Under the general title Energy storage systems using fuel cell modules in reverse mode, the
IEC 62282-8 series consists of the following parts:
• IEC 62282-8-101: Test procedures for the performance of solid oxide single cells and
stacks, including reversible operation
• IEC 62282-8-102: Test procedures for the performance of single cells and stacks with proton
exchange membrane, including reversible operation
• IEC 62282-8-103 : Alkaline single cell and stack performance including reversible operation
• IEC 62282-8-201: Test procedures for the performance of power-to-power systems
• IEC 62282-8-202 : Power-to-power systems – Safety
• IEC 62282-8-301: Power to methane energy systems based on solid oxide cells including
reversible operation – Performance test methods
As a priority dictated by the emerging needs for industry and opportunities for technological

Part 8-201: Energy storage systems using fuel cell modules in reverse
mode – Test procedures for the performance of power-to-power systems
1 Scope
This part of IEC 62282 defines the evaluation methods of typical performances for electric
energy storage systems using hydrogen. It is applicable to the systems that use electrochemical
reaction devices for both power charge and discharge. This document applies to systems that
are designed and used for service and operation in stationary locations (indoor and outdoor).
The conceptual configurations of the electric energy storage systems using hydrogen are shown
in Figure 1 and Figure 2.
Figure 1 shows the system independently equipped with an electrolyser module and a fuel cell
module. Figure 2 shows the system equipped with a reversible cell module.
Indispensable components are an electrolyser module and a fuel cell module, or a reversible
cell module, an overall management system (which includes a data interface and can include a
pressure management), a thermal management system (which can include a thermal storage),
a water management system (which can include a water storage) and a purge gas supply (inert
gas, practically neither oxidizing nor reducing).
NOTE 1 Indispensable components are indicated by bold lines in Figure 1 and Figure 2.
The system can be equipped with either a hydrogen storage or a connection to an external
hydrogen supply infrastructure or a combination of both. There can be a battery and an oxygen
storage, as optional components.
The electrolyser module can comprise one or more electrolysers whether or not of the same
type. Depending on the operating conditions and considering the operation history, the overall
management system can command the concurrent operation of the electrolysers. The fuel cell
module can comprise one or more fuel cells whether or not of the same type. Depending on the
operating conditions and considering the operation history, the overall management system can
command concurrent operation of the fuel cells. The reversible cell module can comprise one
or more reversible cells whether or not of the same type. The fuel cell module can comprise
one or more fuel cells whether or not of the same type. Depending on the operating conditions
and considering the operation history, the overall management system can command
concurrent operation of the reversible cells.
The performance measurement is executed in the defined area surrounded by the bold outside
solid line (system boundary).
NOTE 2 In the context of this document, the term "reversible" does not refer to the thermodynamic meaning of an
ideal process. It is common practice in the fuel cell community to call the operation mode of a cell that alternates
between fuel cell mode and electrolysis mode "reversible".
This document is intended to be used for data exchanges in commercial transactions between
the system manufacturer and customer. Users of this document can selectively execute test
items suitable for their purposes from those specified in this document.
