Abstract:
1. A monopolar membrane-electrode assembly, comprising: an electrolyte membrane in which a plurality of cell regions are formed; an anode supporting body and a cathode supporting body on respective sides of the electrolyte membrane, each of the anode supporting body and the cathode supporting body having a plurality of apertures that corresponds to the cell regions, the anode supporting body and the cathode supporting body respectively further including an anode extension portion and a cathode extension portion that correspond to each other, a plurality of anode current collectors, each comprising a current collecting portion to correspond to each aperture of the anode supporting body to collect current, a conducting portion connected to a side of the current collecting portion, and a connecting line connected to the conducting portion, wherein each anode current collector is integrally formed such that the current collecting portion includes conductive prongs that extend across the corresponding aperture of the anode supporting body, the conducting portion combines the conductive prongs of the current collecting body into a single conductive line that extends along a periphery of the anode supporting body to the anode extension portion and the connecting line is an extension of the conducting portion across the anode extension portion of the anode supporting body; a plurality of cathode current collectors, each comprising a current collecting portion to correspond to each aperture of the cathode supporting body to collect current, a conducting portion connected to a side of the current collector collecting portion, and a connecting line connected to the conducting portion, wherein each cathode current collector is integrally formed such that the current collecting portion includes conductive prongs that extend across the corresponding aperture of the cathode supporting body, the conducting portion combines the conductive prongs of the current collecting body into a single conductive line that extends along a periphery of the cathode supporting body to the cathode extension portion, and the connecting line is an extension of the conducting portion across the cathode extension portion of the cathode supporting body; a plurality of anode electrodes and a plurality of cathode electrodes respectively formed on the anode current collecting portion and the cathode current collecting portion such that unit cells are formed in the cell regions, and wherein each anode current collecting portion is between an anode electrode and the electrolyte membrane and each cathode current collecting portion is between a cathode electrode and the electrolyte membrane; and a circuit unit connected to the connecting lines of the anode current collectors and the cathode current collectors, wherein the circuit unit selectively connects the unit cells in series or in parallel, and selectively connects or disconnects one or more of the unit cells from remaining unit cells.
