Abstract:
An apparatus for consuming gases includes an electrochemical cell comprising a cathode, an anode, and an electrolyte. The cell is operable to produce an electrochemical reaction that forms on the cathode a reactive material comprising at least one of a metal, an alloy, and an intercalation compound. The cell is constructed so that the reactive material formed on the cathode is exposed to the gases that are to be consumed.
Abstract:
An apparatus for forming a vacuum in a sealed enclosure through an electrochemical reaction includes an electrochemical cell comprising a cathode and an anode supported on a solid electrolyte. The solid electrolyte is a Li-ion non-volatile electrolyte containing a dissolved metal salt. The cathode is constructed of a material with which lithium is known to form alloys. The anode is constructed of a lithium-ion containing material. The cell is operable to expose lithium metal on the cathode.
Abstract:
An apparatus (10) for removing oxygen from an enclosed environment (E) includes an electrolyzer (60) operable to remove oxygen from the environment and a zinc-air battery (20) for powering the electrolyzer and removing oxygen from the environment.
