NOVELTY - Apparatus for galvanizing one side of a substrate, in a processing chamber with anodes (6) and circulating electrolyte (8), has a component (2) consisting of an anode support (3) for receiving soluble anode material (or an insoluble anode), a central free space (3) and (as upper part) operating device(s) (5) for adjusting shut-off of electrolyte flow through the chamber via the anode support and free space.    USE - Especially for galvanizing one side of a wafer, solar cell or hybrid substrate (claimed). The apparatus is typically in cup, fountain or cell plater form.    ADVANTAGE - A homogeneous layer thickness distribution is obtained. Soluble or insoluble anodes are utilized economically. Servicing operations can be almost completely automated. Complete cleaning or demetallization of the articles surfaces and cathodic contacts is possible.    DETAILED DESCRIPTION - Apparatus for galvanizing one side of a substrate, in a processing chamber with soluble or insoluble anodes (6) and an electrolyte (8) circulating through the chamber, has a component (2) consisting of an anode support (3) for receiving soluble anode material (or an insoluble anode) and having a central free space (3). The electrolyte-permeable upper part of the component consists of operating device(s) (5) for adjusting shut-off of the flow of electrolyte through the chamber via the anode support and free space. An INDEPENDENT CLAIM is included for a corresponding galvanization method using the apparatus, in which varying current conditions are set on the surface to be electrochemically treated during galvanization of the article and demetallization of the article support, by variation of the volume flow of the circulating electrolyte (8) and by constructional features of the component (2).
