EN IEC 62282-7-2:2021

Fuel cell technologies - Part 7-2: Test methods - Single cell and stack performance tests for solid oxide fuel cells (SOFCs)

This part of IEC 62282 applies to SOFC cell/stack assembly units, testing systems, instruments and measuring methods, and specifies test methods to test the performance of SOFC cells and stacks. This document is not applicable to small button cells that are designed for SOFC material testing and provide no practical means of fuel utilization measurement. This document is used based on the recommendation of the entity that provides the cell performance specification 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 can selectively execute test items suitable for their purposes from those described in this document Users can substitute selected test methods of this document with equivalent test methods of IEC 62282-8-101 for solid oxide cell (SOC) operation for energy storage purposes, operated in reverse or reversible mode.

Technologies des piles à combustible - Partie 7-2: Méthodes d'essai - Essais de performance de cellule élémentaire et de pile pour les piles à combustible à oxyde solide (SOFC)

IEC 62282-7-2:2021 s’applique aux entités d'assemblage de cellules/piles SOFC, aux systèmes d'essai, aux instruments et aux méthodes de mesure, et spécifie des méthodes d'essai afin de vérifier les performances des cellules et des piles SOFC. Le présent document n'est pas applicable aux petites piles boutons qui sont conçues pour les essais de matériaux SOFC et ne prévoient aucun moyen pratique de mesure de l'utilisation de combustible. Le présent document est utilisé en réponse à la recommandation de l'entité qui fournit la spécification des performances des cellules ou pour l'acquisition de données sur une cellule ou une pile afin d'estimer les performances d'un système sur la base de ces données. Dans ce but, les utilisateurs du présent document peuvent choisir d'exécuter des éléments d'essai parmi ceux qui sont décrits ici.Cette première édition annule et remplace l'IEC TS 62282-7-2 parue en 2014. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’IEC TS 62282-7-2:2014: - les utilisateurs peuvent remplacer les méthodes d’essai sélectionnées du présent document par les méthodes d’essai équivalentes de l’IEC 62282-8-101 pour l’utilisation des piles à oxyde solide (SOC – solid oxide cell) à des fins de stockage de l’énergie, en mode inversé ou réversible; - les termes et définitions sont alignés sur les termes et définitions correspondants de l’IEC 62282-8-101; - les symboles sont alignés sur les symboles correspondants de l’IEC 62282-8-101.
