Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 51 N° 43 (Octobre 2012) . - pp. 14229-14235 Titre : Electrochemical characterization of mass transport in porous electrodes Type de document : texte imprimé Auteurs : Quentin de Radiguès, Auteur ; Pierre-Yves Sévar, Auteur ; Frédéric Van Wonterghem, Auteur Année de publication : 2013 Article en page(s) : pp. 14229-14235 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Electrodes Mass transfer Résumé : Mass transport in reticulated vitreous carbon electrodes in flow by mode has been studied with the cathodic deposition of copper as a model reaction. Two methods characterizing mass transport are being compared. The first one relies on determination of the electrorecovery kinetics under mass-transfer limiting conditions in galvanostatic mode. The second method is the determination of the limiting current by a linear potential sweep technique. This technique has been modified to allow for a more unambiguous limiting current determination. In some cases, the modified linear sweep technique can also be used to measure the influence of a gaseous reaction side products on mass transport.
