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.
