▎ 摘　　要

NOVELTY - Electrocatalyst cell stack for water electrolysis capable of high-efficiency electrolyzed water circulation, comprises plate-shaped electrode catalysts (10) that are continuously provided at regular intervals, where the electrode catalyst has a central protrusion type on one surface in which a curved projection (11) is formed to protrude in a streamlined shape in the center of one surface; one-sided upper protrusion in which the curved protrusion is formed to protrude in a streamlined convex shape on one side of the upper surface; one-sided lower protrusion in which the curved protrusion is formed to protrude in a streamlined convex shape on the lower portion of one surface; a curved surface in the center of both sides; double-sided central protrusion type in which the protrusion is formed to protrude in a streamlined convex shape; a double-sided upper protrusion in which the curved protrusion is formed; and a curved protrusion at the lower side of both sides. USE - The electrocatalyst cell stack is useful for water electrolysis capable of high-efficiency electrolyzed water circulation. ADVANTAGE - The convection phenomenon of hydrogen, oxygen gas and water generated during water electrolysis due to the generation of lift is improved. The bubbles do not adhere to the surface of the cell stack, so that the high-efficiency performance is obtained compared to the same electrical energy. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of electrode catalyst for water electrolysis. Electrode catalysts (10) Curved projection (11)
