“…All these results suggest that DHN-70 can be used as alternate membrane material to Nafion 117 in an MFC application. In addition, the membranes prepared in this investigation showed better results in terms of power density as compared to many other hydrocarbon based membranes when incorporated in MFC. − However, it is always not possible to compare the membrane performance owing to different fuel cell configurations and their operating conditions. ,, …”

A hydroxyl group containing new cardo diamine monomer was synthesized, namely 9,9-bis (hydroxy- (4'-amino(3-trifluoromethyl)biphenyl-4-oxy)-phenyl)-9H-fluorene (mixture of isomers, HAPHPF). HAPHPF, along with a sulfonated diamine monomer, 4,4'-diaminostilbene-2,2'-disulfonic acid (DSDSA), was used to prepare a series of new sulfonated copolyimides by polycondensation with 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTDA). The degree of sulfonation (DS < 1) was adjusted by the feed ratio of DSDSA/HAPHPF and the copolymers were named as DHN-XX, where XX denotes the mole percentage of DSDSA (XX = 50, 60, and 70). The copolymers showed high molecular weights. The copolymer structure and composition were confirmed by FTIR and NMR techniques. Copolymer membranes were prepared through solution cast route by using dimethyl sulfoxide as a solvent. The membranes showed high thermal, mechanical, hydrolytic and peroxide radical stability, and low water uptake and low swelling ratios. Well-separated hydrophilic and hydrophobic phase morphology was observed in TEM and AFM images of the copolymer membranes and was further supported by the SAXS studies. The proton conductivity of the DHN-70 was as high as 97 mS cm at 80 °C and the value is significantly higher than that of the nonhydroxylated analogue. The membranes also showed superior microbial fuel cell (MFC) performance, similar like Nafion 117 under similar test conditions. The chemical oxygen demand removal values provide substantial evidence that the fabricated membranes can be utilized in bioelectrochemical systems.

Titanium oxide nano tubes (TNT) were synthesized by hydrothermal method and tungstic acid (ion exchange group) were covalently grafted on its surface. The synthesized tungstic acid functionalized TNT (W-TNT) were characterised by SEM, TEM, XRD analysis for the nano-tubular morphology and the successful grafting of tungstic acid group was confirmed by FTIR and solid state NMR techniques. Composite membranes of different weight percentage W-TNT (2%, 4%, 6% and 8%) and sulfonated poly ether ether ketone (SPEEK) were fabricated which resulted in high ion exchange properties. The prepared composite membranes were characterised by SEM, XRD, FTIR, water uptake, ion exchange capacity and proton conductivity to ensure the aptness of the membranes to be used as electrolyte in fuel cell application. From the studies it was found that SPEEK with 6% W-TNT showed optimum electrochemical properties. Upon testing this membrane in fuel cell as an electrolyte with carbon supported platinum anode and cathode electrodes, a maximum power density of 352 mW cm −2 was achieved at 80 °C. The presence of additional ion exchange groups (tungstic acid) and hollow nature of TNT lead to the improved performance than the plain membrane.

“…A SPEEK composite with cation exchange resin (made with sulfonated styrene‐crosslinked divinylbenzene) was fabricated. [ 93 ] Incorporating the resin had two competing effects: its compact crosslinked structure reduced the water uptake (which ultimately resulted in lower conductivity), whereas its higher IEC had a positive effect on conductivity. The overall effect was that proton conductivity was higher than pristine SPEEK but still lower than Nafion.…”

The adoption of microbial fuel cell (MFC) technology hinges on the development of efficient proton‐exchange membranes (PEMs), which significantly influences fuel cell performance and cost. PEMs have a critical role in preventing oxygen crossover, maintaining electrochemical neutrality, and supporting microorganisms within MFCs. Nafion, the current industry‐standard PEM, grapples with environmental, cost, and performance issues. Although improvements to Nafion have been reported using additives, immersion in heteropolyacids, different pretreatment methods, and UV irradiation, many of the challenges still remain. Herein, the recent developments in the area of alternative PEMs are reviewed and analyzed. Among them, sulfonated aromatic hydrocarbons, particularly sulfonated polyether ether ketone, have emerged as top contenders in terms of scale up and commercial viability. At the same time, membranes based on polyvinyl alcohol, ionic liquids, and natural materials are also being actively researched for various MFC applications. Since most studies are short term and lab scale, there is a need evaluate long‐term stability and economic cost of PEMs in terms of standardized parameters such as power‐to‐cost and normalized energy recovery. Additionally, for emerging low‐energy‐density MFC applications like biosensors and in vivo power sources, PEM properties and design need to be tailored carefully.
