Claim 0:
1. An expanded ion-exchange membrane electrolysis cell, comprising:
an anode plate;
a cathode plate;
at least one bipolar electrode plate disposed between the anode plate and the cathode plate;
a first ion-exchange membrane plate disposed between the anode plate and the at least one bipolar electrode plate;
a second ion-exchange membrane plate disposed between the at least one bipolar electrode plate and the cathode plate;
a surface of the anode plate, a surface of the cathode plate and two surfaces of the at least one bipolar electrode plate respectively having a recessed center, the recess center having a plurality of grooves connected to each other and a plurality of bumps formed between the grooves, wherein the grooves comprise a first set of grooves extending along a first direction and a second set of grooves extending along a second direction different from the first direction, so as to form the bumps arranged in a 2D array;
a sealing gasket disposed next to the cathode plate;
a first separator comprising a flat plate and a support section disposed on the flat plate;
a oxygen chamber formed between the anode plate and the first ion-exchange membrane plate or between the at least one bipolar electrode plate and the second ion-exchange membrane plate; and
a hydrogen chamber formed between the first ion-exchange membrane plate and the at least one bipolar electrode plate or between the second ion-exchange membrane plate and the cathode plate;
wherein a hydrogen outlet channel, an oxygen outlet channel and a water inlet channel are formed in the expanded ion-exchange membrane electrolysis cell, the hydrogen outlet channel is coupled to the hydrogen chamber, and the oxygen outlet channel and the water inlet channel are coupled to the oxygen chamber;
wherein, the first separator is disposed at a connecting channel of the hydrogen chamber to the hydrogen outlet channel, the connecting channel has no bump therein, and the flat plate abuts against and bears the sealing gasket to form a first port in the connecting channel by the support section.
