Abstract
An electrolyzer includes a stack composed of a plurality of upright electrolytic cell units, each unit including an electrolytic cell unit frame bounding a pair of electrode sheets. Each pair of electrode sheets are anode-side and cathode-side partitions having opposed recesses and projections that are engaged in nesting relationship with each other. A gas-liquid separation chamber is provided which is integral with an upper edge of the electrolytic cell unit frame.
Claims10
An electrolyzer, comprising:
- a stack composed of a plurality of upright electrolytic cell units, each including an electrolytic cell unit frame bounding a pair of electrode sheets, said pair of electrode sheets being anode- and cathode-side partitions having opposed recesses and projections that are engaged in nesting relationship with each other;
- and
- a gas-liquid separation chamber which is integral with an upper edge of said electrolytic cell unit frame.
A method of producing an electrolyzer comprising a stack of electrolytic cell units, each including electrode sheets joined to the projections of a partition sheet obtained by pressing together anode- and cathode-side partitions having recesses and projections that are engaged with each other and further including at least one of a gas-liquid separation chamber built up of a member integral with the upper partition of said electrolytic cell unit and an electrolyte dispensing and feeding chamber built up of a member integral with the lower partition of said electrolytic cell unit, wherein each partition is bent down to form said gas-liquid separation or electrolyte dispensing and feeding chamber with a member integral with said partition sheet.
An electrolyzer, comprising:
- a stack of upright electrolytic cell units, each including electrode sheets joined to the ribs of a partition sheet obtained by pressing together anode- and cathode-side partitions having recesses and projections that are engaged with each other, wherein:
- each electrolytic cell unit includes a partition sheet vertically provided with recesses and projections;
- said partition sheet is divided into a plurality of zones in the height direction;
- the recesses in one zone are in line with the ribs in the other zone;
- one recess in one zone communicates with adjacent recesses in the same zone through a passage;
- and
- the recesses in one zone communicate with the recesses in the other zone through fluid-communicating channels.
An electrolyzer, comprising:
- a stack composed of a plurality of upright electrolytic cell units, each including an electrolytic cell unit frame bounding a pair of electrode sheets, said pair of electrode sheets being anode- and cathode-side partitions having opposed recesses and projections that are engaged in nesting relationship with each other;
- and
- an electrolyte dispensing and feeding chamber which is integral with a lower edge of said electrolytic cell unit frame.
