In some embodiments, an apparatus includes a housing and a purge valve. The housing defines a cavity and a lumen extending from a volume of the cavity to a volume outside the cavity. The purge valve is disposed within the lumen and includes an occlusion member. A portion of the occlusion member has a width substantially equal to a width of an end portion of the lumen such that the portion of the occlusion member is disposed within the end portion of the lumen when the purge valve is in a first configuration. The portion of the occlusion member being disposed outside the end portion of the lumen when the purge valve is in a second configuration.

An apparatus is disclosed which includes an electrolytic capacitive element with multiple capacitor sections.

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.

A pressure valve to be arranged in a seal member sealing a casing in which a capacitor element is housed, the pressure valve having a base end positioned within the case and a tip positioned outside the case. The pressure valve includes a tapered portion having a tapered shape. At the top portion of the tapered portion, there is formed a slit able to undergo a state change between a close-state and an open-state by elastic deformation. When the casing internal pressure is less than a certain value, the slit maintains the close-state. When the casing internal pressure has reached the certain value, the slit undergoes a state change to the open-state, whereby the inside and outside of the case communicate with each other and the internal pressure is released from within the case.
