Abstract
Official abstract text for this publication.
A laminate includes an electrode for electrolysis and a membrane laminated on the electrode for electrolysis. The membrane has an asperity geometry on the surface thereof and a ratio a of a gap volume between the electrode for electrolysis and the membrane with respect to a unit area of the membrane is more than 0.8 μm and 200 μm or less.
First claim
Opening claim text (preview).
What is claimed is: 1 . A laminate comprising: an electrode for electrolysis, and a membrane laminated on the electrode for electrolysis, wherein the membrane has an asperity geometry on the surface thereof, and a ratio a of a gap volume between the electrode for electrolysis and the membrane with respect to a unit area of the membrane is more than 0.8 μm and 200 μm or less. 2 . The laminate according to claim 1 , wherein a height difference, which is a difference between a maximum value and a minimum value in the asperity geometry, is more than 2.5 μm. 3 . An electrolyzer comprising the laminate according to claim 1 . 4 . A method for producing a new electrolyzer by arranging a laminate in an existing electrolyzer comprising an anode, a cathode that is opposed to the anode, and a membrane that is arranged between the anode and the cathode, the method comprising: replacing the membrane in the existing electrolyzer by the laminate, wherein the laminate is the laminate according to claim 1 .
