Abstract: An environment control system utilizes oxygen and humidity control devices that are coupled with an enclosure to independently control the oxygen concentration and the humidity level within the enclosure. An oxygen depletion device may be an oxygen depletion electrolyzer cell that reacts with oxygen within the cell and produces water through electrochemical reactions. A desiccating device may be g, a dehumidification electrolyzer cell, a desiccator, a membrane desiccator or a condenser. A controller may control the amount of voltage and/or current provided to the oxygen depletion electrolyzer cell and therefore the rate of oxygen reduction and may control the amount of voltage and/or current provided to the dehumidification electrolyzer cell and therefore the rate of humidity reduction. The oxygen level may be determined by the measurement of voltage and a limiting current of the oxygen depletion electrolyzer cell. The enclosure may be a food or artifact enclosure.

Abstract: A composite ion conducting tube is made by wrapping a support material or ion conducting sheet to from a tube having overlaps of layers that are bonded. The ion conducting sheet or tape used to make the tube may be very thin and the tube may be formed in situ by wrapping the support material and then coating with ion conducting polymer. The ion conducting tubes may be used in a pervaporation module or desalination system. The ion conducting tubes may be spirally wrapped or longitudinally wrapped and may be very thin having a tube wall thickness of no more than 25 microns.

Abstract: A high water transfer electrochemical compressor is described having a ‘n’ transfer of water through the ion conducting membrane of greater than one. This may be accomplished by reducing the equivalent weight of the ion conducting polymer, such as an ionomer to less than about 900 and/or by reinforcing the low equivalent weight ionomer with a support material, such as an expanded polytetrafluoroethylene. This may be accomplished by making components of the electrochemical cell hydrophilic including the electrodes and/or gas diffusion media. This may be accomplished by adding a flow component to a feed fluid or refrigerant, such as an alcohol, acid, or acetone, for example. A flow component may modify an electrode and/or the ion conducting media, by rendering them hydrophilic. A flow component may swell an ion conducting media enable high transport of the working fluid.

Abstract: An electrochemical compression system utilizes an electrolyzer to electrolyze an electrochemically active working fluid, at a first pressure, into decomposition products that are reformed back into said electrochemically active working fluid by a fuel cell, at a higher pressure. Water may be electrolyzed into hydrogen and oxygen and stored in reservoir tanks at an elevated pressure and subsequently provided to a fuel cell for reforming. The hydrogen is provided to the anode side of a polymer electrolyte membrane fuel cell and the oxygen is provided to the cathode side. Water is reformed on the cathode side of the fuel cell at a higher pressure than the inlet to the electrolyzer. This pressure differential enable flow of the electrochemically active working fluid through a conduit from the cathode to the electrolyzer. This flow of fluid may be used in a heat transfer system.

Abstract: A cooling systems utilizes an organic ionic salt composition for dehumidification of an airflow. The organic ionic salt composition absorbs moisture from an inlet airflow to produce an outlet airflow with a reduce moisture from that of the inlet airflow. The organic ionic salt composition may be regenerated, wherein the absorbed moisture is expelled by heating with a heating device. The heating device may be an electrochemical heating device, such as a fuel cell, an electrochemical metal hydride heating device, an electrochemical heat pump or compressor, or a condenser of a refrigerant cycle, which may utilize an electrochemical pump or compressor. The efficiency of the cooling system may be increased by utilization of the waste heat the cooling system. The organic ionic salt composition may circulate back and forth or in a loop between a conditioner, where it absorbs moisture, to a regenerator, where moisture is desorbed by heating.

Abstract: An electrochemical heat transfer device utilizes an electrochemical hydrogen compressor to pump hydrogen into and out of a reservoir having a metal hydride forming alloy therein. The absorption of hydrogen by the metal hydride forming alloy is exothermic, produces heat, and the desorption of the hydrogen from the metal hydride forming alloy is endothermic and draws heat in. An electrochemical hydrogen compressor may be configured between to reservoirs and pump hydrogen back and forth to form a heat transfer device. A heat exchange device may be coupled with the reservoir or may comprise the outer surface of the reservoir to transfer heat to an object or to the surroundings. A closed loop may be configured having two reservoirs and one or two electrochemical hydrogen compressors to pump the hydrogen in a loop around the system.

Abstract: An ionic liquid desiccant system utilizes an ionic liquid desiccant to draw moisture from a working fluid, such as air that flow into an enclosure, such as a home. The desiccant may be mixed with the working fluid or a separator that allows moisture transport therethrough may be configured between the ionic liquid desiccant and the working fluid. The ionic liquid desiccant system may be part of an air conditioning system and may remove the moisture from air that is cooled by flowing over an evaporator or heat exchanger coupled with the evaporator. The ionic liquid desiccant may be pumped from a desiccant chamber to a regenerator chamber to remove absorbed moisture. A dual-purpose chamber may act as a desiccant chamber and as a regenerator chamber. A refrigeration system may have an electrochemical compressor and may utilize metal hydride heat exchangers.
