“…Similarly, porous nanocomposite CEMs with inorganic functional groups have been prepared and tested for RED applications [84,85,194] properties by tuning preparation conditions. This membrane has been investigated for several applications including fuel cells [195][196][197][198][199]. The applications have also been investigated for RED by Kim et al [168] Other polymeric materials recently used for fabrication of IEMs for RED application involve poly(2,6-dimethyl-1,4-phenylene oxide) (SPPO) [200], polyethylene [201] and poly(arylene ether sulfone) (PAES) [166,202].…”

Salinity gradient energy is currently attracting growing attention among the scientific community as a renewable energy source. In particular, Reverse Electrodialysis (RED) is emerging as one of the most promising membrane-based technologies for renewable energy generation by mixing two solutions of different salinity. This work presents a critical review of the most significant achievements in RED, focusing on membrane development, stack design, fluid dynamics, process optimization, fouling and potential applications. Although RED technology is mainly investigated for energy generation from river water/seawater, the opportunities for the use of concentrated brine are considered as well, driven by benefits in terms of higher power density and mitigation of adverse environmental effects related to brine disposal. Interesting extensions of the applicability of RED for sustainable production of water and hydrogen when complemented by reverse osmosis, membrane distillation, bioelectrochemical systems and water electrolysis technologies are also discussed, along with the possibility to use it as an energy storage device. The main hurdles to market implementation, predominantly related to unavailability of high performance, stable and low-cost membrane materials, are outlined. A techno-economic analysis based on the available literature data is also performed and critical research directions to facilitate commercialization of RED are identified.

“…Hot-press treatment for anion-conductive membrane by plasma-polymerization Figure 6 shows that the translucent plasma polymerized membrane became transparent when the membrane was hot-pressed. This was expected because the polymer and substrate were pressed and the large pores decreased (13). Table III shows the thickness, water uptake, methanol permeability and transport number of the membranes.…”

An anion exchange membrane for use in a direct methanol alkaline fuel cell (DMAFC) was fabricated by the plasma-polymerization method. Plasma polymerization with 4-vinylpyridine and hexafluoropropene followed by quaternization using 1-bromopropane was conducted in order to prepare an anion exchange membrane using a porous film. Plasma polymerized membranes on various porous films were characterized by their water uptake, ion conductivity, methanol permeability and OHtransport number. TGA curves indicated that the membrane had a mass loss when the temperatures rose to 145 °C. The methanol permeability decreased from 0.25×10 -6 to 0.01×10 -6 cm 2 /s and the OH -transport number increased from 0.89 to 0.93 by hot-press treatment because the porosity of the membrane decreased due to the hot-press treatment. This indicated that the hot-press treatment enhanced the selectivity of the mass transport of the membrane, and the hot-press treatment increased the conductivity of the membrane from 33.5 to 39.3 mS/cm because the membrane became thin by the hot-press treatment. The OCV was improved by the hot-press treatment due to the increased mass transport selectivity.

“…Physical methods such as polymer blending [17], pore filling [18], and van der Waals interaction tuning [19] have also been used to prepare physically reinforced HEMs. In polymer blending, a reinforcing material (usually a hydrophobic and nonionic polymer, for example, polysulfone) is blended with a polymer that contains cationic functional groups.…”
