ABSTRACT:
An apparatus for the anodic oxidation of aluminum permits the recovery of hydrogen generated from the cathode. The cathode is positioned within a tubular member provided with a multiplicity of small openings each having a size sufficient to allow passage of an electrolytic solution therethrough but to prevent passage of hydrogen bubbles therethrough. Thereby, the hydrogen is collected in the upper space above the surface of the electrolytic solution in the tubular member and is discharged therefrom through a conduit opening thereinto.
