Fuel cell technologies - Part 8-101: Energy storage systems using fuel cell modules in reverse mode - Test procedures for the performance of solid oxide single cells and stacks, including reversible operation

IEC 62282-8-101:2020 addresses solid oxide cell (SOC) and stack assembly unit(s). It provides for testing systems, instruments and measuring methods to test the performance of SOC cell/stack assembly units for energy storage purposes. It assesses performance in fuel cell mode, in electrolysis mode and/or in reversible operation. This document is intended for data exchanges in commercial transactions between cell/stack manufacturers and system developers or for acquiring data on a cell or stack in order to estimate the performance of a system based on it. Users of this document may selectively execute test items suitable for their purposes from those described in this document. Users can also substitute selected test methods of this document with equivalent test methods of IEC TS 62282-7-2 for SOC operation in fuel cell mode only.

Technologies des piles à combustible - Partie 8-101: Système de stockage de l’énergie utilisant des modules à piles à combustible en mode inversé - Procédures d'essai pour la performance des cellules élémentaires et des piles à oxyde solide, comprenant le fonctionnement réversible

l'IEC 62282-8-101:2020 traite des entités d'assemblage de cellules/piles à oxyde solide (SOC). Elle fournit des méthodes de mesure et des instruments aux systèmes afin de soumettre à l’essai la performance des entités d’assemblage de cellules/piles SOC en matière de stockage de l’énergie. Elle évalue la performance des piles à combustible, des piles à électrolyse et/ou en fonctionnement réversible. Le présent document est destiné à être utilisé pour les échanges de données des transactions commerciales entre les fabricants de cellules/piles et les développeurs système, ou pour l’acquisition de données relatives à une cellule ou une pile permettant d’estimer la performance d’un système qui se base sur cette cellule/pile. Les utilisateurs du présent document peuvent choisir les éléments d’essai à exécuter selon leurs objectifs à partir de ceux décrits dans le présent document. Les utilisateurs peuvent également substituer les méthodes d’essai choisies dans le présent document avec des méthodes d’essai équivalentes données dans l'IEC TS 62282-7-2 pour les SOC fonctionnant en mode combustible seulement.
