Abstract

Disclosed is an integrally combined electrical current carrier, circulation chamber and frame (CCF) formed as a single or double part (CCF) for use in unipolar electrochemical devices, such as a filter press electrolyser apparatus. The CCF is structured to define an internal circulation chamber for circulation of electrolyte, products, and reactants as well as apertures which form flow passageways when the filter press device is assembled. Affixed on opposed surfaces of the CCFs are electrically conductive planar electroactive structures which are in electrical contact with the CCF. The circulation chamber is formed by the depth of the CCF itself between opposing electroactive structures. Multiple CCFs are assembled and compressed together to form the filter press electrolyser apparatus. The flow passageway apertures within the assembled filter press electrolyser are aligned to form flow pathways, located above and below the circulation chambers. Reactants and electrolyte are input along the bottom flow pathways. When power is applied to the CCFs and electroactive structures, the reactants, once they flow into the circulation chamber with the electrolyte, undergo redox reactions to produce the products which are then collected and exit the electrolyser in the upper flow pathways.
