Abstract

See full text

The present invention relates to an electrode for use in an electrochemical cell, such a flow battery, especially a zinc-bromine flow battery or a hydrogen/bromine flow battery, and methods for manufacturing and using the electrode. The claimed electrode comprises a metal substrate and a catalytic coating applied onto said substrate wherein the catalytic coating comprises a Ru-rich mixture of ruthenium and platinum comprising preferably 70-80 mol% Ru, 1-5 mol% Pt and 17-25 mol% Ir. The claimed catalytic coating composition exhibits a surprisingly high voltage efficiency and operating lifetime despite its relatively low Ir/Ru and Pt/Ru ratios. The underlying metal substrate is for example a porous Ti layer or a layer comprising titanium suboxides TixOy.
