Abstract:
An electrochemical half-cell comprising:(a) a membrane; (b) an electrode for generating gas as an anode or a cathode; (c) a supporting structure for joining the electrode, wherein the supporting structure divides the interior of the half-cell into (i) a first set of vertically arranged channels, which face the electrode, for flowing an electrolyte upwards, and (ii) a second set of vertically arranged channels, which face away from the electrode, for flowing the electrolyte downward, wherein the first set of vertically arranged channels and the second set of vertically arranged channels have top ends and bottom ends, the first set of vertically arranged channels have a cross-sectional constriction formed by a guide structure, at the top ends of the first set of vertically arranged channels, and the first vertically arranged channels and the second vertically arranged channels are connected to one another at their top ends and their bottom ends, wherein the supporting structure is attached to a guide structure and the supporting structure and the guide structure form one piece, and wherein the cell has an interior, a gas inlet, and a gas outlet.
