Abstract
Official abstract text for this publication.
The purpose of the present invention is to provide an electrochemical element that can withstand prolonged use, with little damage or degradation due to the pressure of hydrogen gas generated, even when used for prolonged periods of time. This electrochemical element is equipped with a hydrogen-releasing film and has a laminated body in which an anode and a cathode are laminated with a separator interposed therebetween. The hydrogen-releasing film contains a metal layer, the separator contains pulp, and the total sulfur component content in the separator is 400 ppm or less as determined by quartz tube combustion gas absorption ion chromatography.
First claim
Opening claim text (preview).
1 . An electrochemical element equipped with a hydrogen-releasing film and having a laminated body in which an anode and a cathode are laminated with a separator interposed therebetween, wherein the hydrogen-releasing film contains a metal layer, the separator contains pulp, and the total sulfur component content in the separator is 400 ppm or less as determined by quartz tube combustion gas absorption ion chromatography. 2 . The electrochemical element according to claim 1 , wherein the metal layer is an alloy layer containing a Pd alloy. 3 . The electrochemical element according to claim 2 , wherein the Pd alloy contains 20 to 65 mol % of a group 11 element. 4 . The electrochemical element according to claim 3 , wherein the group 11 element is at least one kind selected from the group consisting of Au, Ag, and Cu. 5 . The electrochemical element according to claim 1 , wherein the hydrogen-releasing film has a support on one side or both sides of the metal layer. 6 . The electrochemical element according to claim 1 , which is an aluminum electrolytic capacitor or a lithium-ion battery.
