Abstract[English]
A process for the manufacture of an anode layer for a polymer electrolyte membrane electrolyser, the process comprising the steps of: (i) forming a catalyst ink comprising an iridium- and / or ruthenium-containing OER catalyst, an ionomer, a solvent, and a cellulose compound; (ii) applying the catalyst ink to a substrate to form the anode layer; and (iii) drying the anode layer. Also described are anode layers for a polymer electrolyte membrane electrolyser, the anode layer comprising an iridium - and/or ruthenium-containing OER catalyst, an ionomer, and a cellulose compound.[French]
L'invention concerne un procédé de fabrication d'une couche d'anode pour un électrolyseur à membrane électrolytique polymère, le procédé comprenant les étapes consistant à : (i) former une encre catalytique comprenant un catalyseur de réaction de libération d'oxygène (OER) contenant de l'iridium et/ou du ruthénium, un ionomère, un solvant et un composé cellulosique ; (ii) appliquer l'encre catalytique sur un substrat pour former la couche d'anode ; et (iii) sécher la couche d'anode. L'invention concerne également des couches d'anode pour un électrolyseur à membrane électrolytique polymère, la couche d'anode comprenant un catalyseur d'OER contenant de l'iridium et/ou du ruthénium, un ionomère et un composé cellulosique.
