The paper describes results of preliminary experimental observations on a fluidized bed electrode. This consists of a bed of electrically conducting spherical particles fluidized by electrolyte flow. The present results are confined to the cathodic reduction of m‐nitro benzene sulfonic acid to metanilic acid in aqueous sulfuric acid. The investigations have demonstrated that charge is dispersed throughout the bed such that an electrochemical reaction takes place at the particulate surface. Results show that the fluidized electrode is capable of scaling up electrode processes having low exchange currents to give high over‐all currents in relatively small cell volumes.
