β¦ Synopsis
Fluidiied bed electrodes are described physically and in terms of an ek~trical analogue. Measurements of potential on a typical particle in the bed with respect to the potential imposed on the feeder are recorded. Current/potential curves for the ferrous/ferric reaction and the methanol oxidation are given. Low electronic conductivity between the particles in the bed has been found to be a limiting factor in its operation. R&mm&On a d&-it les tlectrodes au lit fluidique physiquement et en termes d'analogue &Iectrique. On a obtenu Ies mbures de poteatiel sur une particle typique dans le lit fluidique par rapport au potentiel impos& par le chargeur. On pr&ente Ies courbes de courant/tension pour la Action ferrous/ferrique et I'oxydation de methanole. Le facteur qui limite sa fonction est la petite Con-ductibilib5 entre les particules dans le lit. Zusammenfassung-Schwebebett-Elektroden werden in physikalischer Hinsicht beschrieben, und es wird ein elektrisches Analogon dafiir aufgestellt.
