▎ 摘　　要

NOVELTY - An electrocatalyst cell stack comprises plate-shaped electrode catalysts continuously provided at regular intervals. The electrode catalyst contains a central protrusion type in one surface in which a curved projection is formed to protrude in a streamlined shape in the center of one surface, one-sided upper protrusion in which the curved projection protrudes convexly in a streamlined shape on one side of the upper surface, a one-sided lower protrusion in which the curved projection is formed to protrude in the streamlined shape on the lower side of one surface, a double-sided central protrusion in which the curved projection protrudes in a streamlined convex form at the center of both sides, a double-sided upper protrusion in which the curved projection protrudes in a streamlined convex shape on both sides of the upper portion, and double-sided lower protrusions in which the curved projections are formed to protrude in a streamlined convex shape on the lower sides of both surfaces. USE - Electrocatalyst cell stack for water electrolysis. Uses include but are not limited to fuel reduction devices, washing markets, household appliances, hydrogen-oxygen generators and hydrogen cars. 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.
