摘要： An ion exchange polymer has an ionomer structure containing poly(phenylene) compound integrated with functionalized poly(fluorene). The ion conducting co-polymer includes a poly(fluorene) compound and a poly(phenylene) compound covalently bonded together. The poly(fluorene) compound has a 9H-fluorene structure that is a polycyclic aromatic hydrocarbon having a center ring with five carbon atoms, and a benzene ring on each of opposing sides of said center ring. The poly(phenylene) compound is covalently bonded to each of the pair of benzene rings of the poly(fluorene) compound. A pair of sidechains extends from the center ring of the poly(fluorene) compound to a respective terminal group. The terminal groups are configured on sidechains of the poly(fluorene) compound and can be converted into functional groups such as quaternary ammonium or n-methyl piperidine functional groups. The ion exchange polymer may include a porous scaffold support.

摘要： An electrochemical compressor utilizes an anion conducting layer disposed between an anode and a cathode for transporting a working fluid. The working fluid may include carbon dioxide that is dissolved in water and is partially converted to carbonic acid that is equilibrium with bicarbonate anion. An electrical potential across the anode and cathode creates a pH gradient that drives the bicarbonate anion across the anion conducting layer to the cathode, wherein it is reformed into carbon dioxide. Therefore, carbon dioxide is pumped across the anion conducting layer. The compressor may be part of a refrigeration system that pumps the working fluid in a closed loop through a condenser and an evaporator.

摘要： A hydride heat engine produces electricity from a heat source, such as a solar heater. A plurality of metal hydride reservoirs are heated by the heating device and a working fluid comprises hydrogen is incrementally move from one metal hydride reservoir to a success metal hydride reservoir. The working fluid is passed, at a high pressure, from the last of the plurality of metal hydride reservoirs to an electro-chemical-expander. The electro-chemical-expander has an anode, a cathode, and an ionomer therebetween. The hydrogen is passed from the anode at high pressure to the cathode at lower pressure and electricity is generated. The solar heater may be a solar water heater and the hot water may heat the metal hydride reservoirs to move the hydrogen. The working fluid may move in a closed loop.

摘要： An ultra-thin anion exchange membrane incorporates functional additives to provide improved water management. Without the functional additives the ultra-thin membrane may have high cross-over and not be effective for many applications. A composite anion exchange membrane includes a porous scaffold support such as a porous polymer. The anion exchange polymer may be coupled to the porous scaffold, such as by being imbibed into the pores of the porous scaffold. The functional additives may contribute to increase water production, water retention, back-diffusion and reduce the gas crossover. A functional additive may include a reactive species, including a catalyst that reacts with oxygen or hydrogen, a plasticizer, a hygroscopic material and/or a radical scavenger.

摘要： Composite polyether block amide (PEBA) copolymer tubes incorporate an ultra-thin PEBA extruded layer that enables rapid moisture transfer and exchange through the tube. An extruded composite PEBA film may include a porous scaffold support and may be formed or incorporated into the composite PEBA tube. An extruded PEBA may be melted into pores of a porous scaffold support. Extruded PEBA may be wrapped on a mandrel or over a porous scaffold support to form a composite PEBA tube. A film layer may be applied over a wrapped composite PEBA film to secure the layers together. A support tube may be configured inside or outside of the PEBA tube.
