    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.

    Abstract: An electrochemical cell 10 comprising a membrane electrode assembly having gas pervious anode (120, fig 1) and cathode (122, fig 1) and an electrolytic membrane (124, fig 1) disposed between and in electrical contact with the anode and cathode allowing passage of a working fluid. The cell further comprises a bipolar plate (20, fig 22) coupled to the anode side 24 of the MEA which has a plurality of port openings 49 along the length of the plate for the delivery of a working fluid to the anode. At least a portion of a working fluid is transferred across the membrane electrode assembly. The anode bipolar plate preferably has an aspect ratio of length to width of at least 2 and the openings cover at least 50% of the anode length. The electrochemical cell is preferably configured in an enclosure (71, fig 22) at less than atmospheric pressure. The enclosure is preferably hermetically sealed. The electrochemical cell may be configured in a heat transfer system in which the working fluid comprises a polar solvent such as methanol that acts as a condensable refrigerant and hydrogen which acts as the electrochemically active component.
