Title:
CAPACITOR AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2019/035454
Kind Code:
A1
Abstract:
The purpose of the invention is to suppress the production of molecular hydrogen from atomic hydrogen generated in a capacitor, and thereby suppress an increase in pressure in the capacitor caused by an increase in molecular hydrogen. This capacitor (2) comprises: a capacitor element (6) formed by winding a positive electrode foil (14) and a negative electrode foil (16); and an outer case (4) that houses therein the capacitor element. A hydrogen reaction film (22) that reacts with atomic hydrogen generated inside the outer case is formed on a surface of the negative electrode foil.
