Fuel cell technologies - Part 8-201: Energy storage systems using fuel cell modules in reverse mode - Test procedures for the performance of power-to-power systems

IEC 62282-8-201:2020 defines the evaluation methods of typical performances for electric energy storage systems using hydrogen. This 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. There are an electrolyser, a hydrogen storage and a fuel cell, or a reversible cell, a hydrogen storage and an overall management system (which may include a pressure management) as indispensable components. There may be a battery, an oxygen storage, a heat management system (which may include a heat storage) and a water management system (which may include a water storage) as optional components. The performance measurement is executed in the area surrounded by the outside thick solid line square (system boundary).

l'IEC 62282-8-201:2020 définit les méthodes d'évaluation des performances typiques des systèmes de stockage de l'énergie électrique utilisant de l'hydrogène. Ces méthodes s'appliquent aux systèmes qui utilisent des dispositifs à réaction électrochimique à la fois pour la charge électrique et la décharge électrique. Le présent document s'applique aux systèmes conçus et utilisés pour l'entretien et le fonctionnement dans des emplacements stationnaires (intérieur et extérieur). La Figure 1 et la Figure 2 représentent les configurations conceptuelles des systèmes de stockage de l'énergie électrique utilisant de l'hydrogène. La Figure 1 présente un système indépendant équipé d'un module électrolyseur et d'un module à pile à combustible. La Figure 2 représente le système équipé d'un module à cellule réversible. Un électrolyseur, un système de stockage de l'hydrogène et une pile à combustible, ou une cellule réversible, un système de stockage de l'hydrogène et un système de gestion global (pouvant inclure la gestion de la pression) constituent les composants indispensables. Une batterie, un système de stockage de l'oxygène, un système de gestion thermique (pouvant inclure le stockage thermique) et un système de gestion de l'eau (pouvant inclure le stockage de l'eau) constituent les composants facultatifs. Le mesurage des performances s'effectue dans la zone délimitée par le carré extérieur à traits pleins épais (limites du système).

FOREWORD

1) The International Electro technical Commission (IEC) is a worldwide organization for standardization comprising

all national electro technical 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.

INTRODUCTION

This part of IEC 62282 describes performance evaluation methods for electric energy storage

systems using hydrogen that employ electrochemical reactions both for water/steam electrolysis

and electric generation.

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 targeting 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.

IEC 62282-8 (all parts) 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 membranes, 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 62282-8-300 (all parts) : Power-to-substance systems

As a priority dictated by the emerging needs for industry and opportunities for technological

development, IEC 62282-8-101, IEC 62282-8-102 and IEC 62282-8-201 have been initiated

jointly and firstly. These parts are presented as a package to highlight the need for an integrated

approach as regards the system's application (i.e. a solution for energy storage) and its

fundamental constituent components (i.e. fuel cells operated in reverse or reversing mode).

IEC 62282-8-103, IEC 62282-8-202 and IEC 62282-8-300 (all parts) are suggested but are left

for initiation at a later stage.

FUEL CELL TECHNOLOGIES –
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. This 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. There are an electrolyser, a hydrogen storage and a fuel cell, or a reversible cell, a

hydrogen storage and an overall management system (which may include a pressure

management) as indispensable components. There may be a battery, an oxygen storage, a heat

management system (which may include a heat storage) and a water management system

(which may include a water storage) as optional components. The performance measurement is
