The film layer may have an A2B2O7 structure where A is Mg, Ca, Sr, Ba or combination of these, and where B is Pt, Ir, Ru, Rh or combination of these. Preferably the hydrating solution is distilled water or a sulphuric acid solution, and the hydrophilic membrane is a perfluorosulphonic acid. The electrodes may comprise titanium, 316L stainless steel, or niobium. Also disclosed is an electrochemical compressor that comprises: (a) an anion exchange membrane; (b) a film layer applied to the membrane; (c) two gas diffusion layers; (d) two plates; (e) two current collecting end plates; and (f) a catalytic transport fluid.

Abstract: An environment control system (10) that utilizes oxygen and humidity control devices that are coupled with an enclosure (50) to independently control the oxygen concentration and the humidity level within the enclosure is described. An oxygen depletion device may be an oxygen depletion electrolyser cell (16) that reacts with oxygen within the cell and produces water through electrochemical reactions. The cell comprises an integral membrane electrode assembly (MEA). A desiccating device may be a dehumidification electrolyzer cell (12), a desiccator, a membrane desiccator or a condenser. A controller (81) may control the amount of voltage and/or current provided to the oxygen depletion electrolyzer cell and therefore the rate of oxygen reduction. It may also 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. A sensor (82) may be provided to measure humidity (83). The enclosure may be a food or artifact enclosure. The system may be used in a continuous positive airway pressure machine (CPAP).

Abstract: The tube comprises a composite 50 micrometre thick composite film comprising a polyether block amide copolymer (PEBA) 48 attached to a porous scaffold support 10. The composite film is formed into a tube with part of the film forming an overlap area (58, figures 6, 7) that is fused. A polymeric layer is applied to a surface of the composite film. Preferably the composite film is at most 25 (5) µm thick and the overlap area comprises no more than 30 (10)% of the outside surface. The support 10 is preferably expanded polytetrafluoroethylene (PTFE), polyethylene or polypropylene (PP). The preferred tube includes a biocide to prevent mould formation. The tube is preferably formed by spiral (figure 6) or longitudinal (figure 7) winding of the composite film. A pervaporation module has water flowing through the tube and fluid flow over the tube, wherein water vapour is fed to the fluid. They can be used to humidify gas, in medical, analytical, oil and gas application.

Abstract: An ozone (O3) generator system 10 that utilizes an electrochemical cell 12 to produce and control ozone concentrations within an enclosure or to supply ozone to a flow conduit is described. The enclosure 50 may be coupled with a flow conduit that carries the produced ozone to a desired location. The enclosure 50 may also be a sterilization chamber, and the concentration of ozone produced by the ozone generating system can sterilize articles within the enclosure. An oxygen control electrolyser cell (Figure 2, 16) and/or humidity control electrolyzer cell may be coupled with the enclosure to further control the environment of the enclosure. A humidity control electrolyzer cell may be fluidly coupled with the ozone generator to supply humidity for reaction on the anode of the ozone generator a humidity sensor 83 may also be provided . The ozone generator comprises an electrochemical cell 12 with a control system (Figure 4, 81) where the cell 12 may comprise an anode 20 and cathode 40 separated by a proton exchange membrane (PEM) 32 or membrane electrode assembly (MEA). The system 10 can also include a fan to force a flow of air over the anode. Multiple cells (Figure 5) may be provided in the system 10.

Abstract: An ion conducting tube 10 comprises a composite ion conducting sheet 40 comprising a permeable support material and an ion conducting polymer coupled to the support material, wherein an outer layer of the sheet is attached to an inner layer of the sheet to form an overlap area 24. The ion conducting tube may be longitudinally wrapped with the overlap area extending longitudinally along the length of the tube or may be spirally wrapped (figure 2). The support material is preferably expanded polytetrafluorethylene. A process for making the ion conducting tube comprises wrapping the composite ion conducting sheet around a mandrel (54, figure 4) and bonding the sheet together. A further disclosed method for making an ion conducting tube comprises wrapping a permeable support material around a mandrel, coating the wrapped mandrel with an ion conducting polymer and bonding overlap areas. The ion conducting tube may be used in apparatus for drying or humidifying gases for electrochemical, medical, analytical and oil and gas applications. The ion conducting tube may also be used in pervaporation modules.

Abstract: A composite ion exchange membrane 60 is made by combining e.g. coating or imbibing into pores an ionomer with porous non-permeable (Gurley Densometer reading less than 500 seconds) polyolefin, such as polyethylene or polypropylene and used in the core of an energy recovery ventilator. The energy recovery ventilator may comprise corrugated or pleated supports for supporting the composite ion exchange membrane which has an intake side and an opposite extract side and an intake 40, an exhaust 44, an extract air inlet 50 and a supply air outlet 54. The air flow into the energy recovery ventilator may be modified to actively create non-laminar flow using twisters. The membrane may have a thickness of less than 25 microns.
