Abstract
Official abstract text for this publication.
The purpose of the present invention is to provide a hydrogen-releasing film and a hydrogen-releasing laminated film which are less susceptible to embrittling at an ambient operating temperature of an electrochemical element. This hydrogen-releasing film is characterized by containing a Pd—Cu alloy, and the Cu content in the Pd—Cu alloy being at least 30 mol %.
First claim
Opening claim text (preview).
1 . A hydrogen-releasing film, comprising an alloy wherein the alloy is a Pd—Cu alloy, and the content of Cu in the Pd—Cu alloy is 30 mol % or higher. 2 . The hydrogen-releasing film according to claim 1 , wherein the content of Cu in the Pd—Cu alloy is 30 to 65 mol %, and the film thickness t and the film area s satisfy the following equation 1: t/s< 16.4 m −1 . 3 . A hydrogen-releasing laminated film, wherein a support is provided on one side or both sides of the hydrogen-releasing film according to claim 1 . 4 . The hydrogen-releasing laminated film according to claim 3 , wherein the support is a porous body having an average pore diameter of 100 μm or less. 5 . The hydrogen-releasing laminated film according to claim 3 , wherein the raw material of the support is a polytetrafluoroethylene or a polysulfone. 6 . A safety valve for an electrochemical element, wherein the valve is provided with the hydrogen-releasing film according to claim 1 . 7 . An electrochemical element, wherein the element is provided with the safety valve according to claim 6 . 8 . The electrochemical element according to claim 7 , wherein the electrochemical element is an aluminum electrolytic capacitor or a lithium ion battery. 9 . A hydrogen-releasing method using the hydrogen-releasing film according to claim 1 . 10 . The hydrogen-releasing method according to claim 9 , wherein hydrogen is released under the circumstances of 150° C. or less.
