Electrode structure for electrolyzer

An electrode structure comprising:

• an electrode plate;
• a flow path guide disposed on one side of the electrode plate along the circumference of the electrode plate;
• a lower through hole passing through the electrode plate and the flow path guide at a lower portion thereof;
• a first flow path allowing the flow path guide and the lower through hole to communicate with each other;
• an upper through hole passing through the electrode plate and the flow path guide at an upper portion thereof;
• a second flow path allowing the flow path guide and the upper through hole to communicate with each other;
• a reaction unit in which the flow path guide is not provided on one side of the electrode plate;
• and
• a third flow path allowing the reaction unit and the flow path guide to communicate with each other, which is provided in at least one of a lower inner wall, a side inner wall, and an upper inner wall of the flow path guide,
• wherein the reaction unit includes an activation unit in which a liquid-phase material introduced into the reaction unit through the third flow path disposed in the lower inner wall of the flow path guide is electrolyzed, and an inactivation unit located above the activation unit so that a gas-phase material generated from the activation unit stays,
• wherein the third flow path located under the surface of the liquid-phase material provides a route through which raw material introduced into the flow path guide through the first flow path moves to the activation unit, a route through which a liquid-phase electrolysis product generated in the activation unit moves into the flow path guide, and a route through which a portion of the liquid-phase electrolysis product moving into the flow path guide is circulated and returned to the activation unit,
• wherein the third flow path located above the surface of the liquid-phase material provides a route through which the gas-phase material moves into the flow path guide.
