Abstract: An electrochemical cell comprising a relatively thin strip of anode material, first and second electrolyte layers coated on the opposing surfaces of the anode strip, first and second relatively thin strips of cathode material contacting the first and second electrolyte layers, thereby forming a laminate strip with the electrolyte layers and anode strip and a single cathode current conductor strip. The laminate strip is deformed such that both of the first and second strips of cathode material contact the single cathode current conductor strip along substantially the entire length thereof.

Abstract: An all-solid state double layer capacitor and an all-solid state multicell electrochemical device are disclosed. The electrolyte material employed in the devices consists of an ionically conductive polymer such as polyethylene oxide with an inorganic salt which renders the polymer material ionically conductive.

Abstract: A pressure control unit comprises a central reference chamber in which the gas pressure is adjustable and one or more control chambers, each of which is separated from the reference chamber by a membrane system which consists of two interconnected membranes having a predetermined ratio of their surface areas. Each membrane system is connected to a valve for controlling the flow of a gas to the respective control chamber whereby the pressure therein varies in proportion to the reference pressure.
