“…The high performance of the SPEEK nanocomposite was obtained using 7.5% SiO2 in the polymer matrix (Sivasankaran and Sangeetha, 2015). For improving SPEEK, Shabani et al (2019) suggested adding GO nanosheets to the SPEEK mixture during synthesis. They claimed that oxygen cross-over of the nanocomposite membrane was about 50% lower than that of Nafion 117 while its conductivity was 25% higher.…”

Materials at the nanoscale show exciting and different properties. In this review, the applications of nanomaterials for modifying the main components of microbial fuel cell (MFC) systems (i.e., electrodes and membranes) and their effect on cell performance are reviewed and critically discussed. Carbon and metal-based nanoparticles and conductive polymers could contribute to the growth of thick anodic and cathodic microbial biofilms, leading to enhanced electron transfer between the electrodes and the biofilm. Extending active surface area, increasing conductivity, and biocompatibility are among the significant attributes of promising nanomaterials used in MFC modifications. The application of nanomaterials in fabricating cathode catalysts (catalyzing oxygen reduction reaction) is also reviewed herein. Among the various nanocatalysts used on the cathode side, metal-based nanocatalysts such as metal oxides and metal-organic frameworks (MOFs) are regarded as inexpensive and high-performance alternatives to the conventionally used high-cost Pt. In addition, polymeric membranes modified with hydrophilic and antibacterial nanoparticles could lead to higher proton conductivity and mitigated biofouling compared to the conventionally used and expensive Nafion. These improvements could lead to more promising cell performance in power generation, wastewater treatment, and nanobiosensing. Future research efforts should also take into account decreasing the production cost of the nanomaterials and the environmental safety aspects of these compounds.

“…[3][4][5][6] Among the various fuel cells, proton exchange membrane fuel cells (PEMFC) possess beneficial features such as high energy density, sustained operation, lower operating temperature, cost, pollution and fast start up. [7][8][9][10][11][12] The proton exchange membrane (PEM) is a key component in the system, which functions as an electrolyte for transferring protons from the anode to the cathode as well as providing a barrier to the passage of electrons and gas cross-leaks between the electrodes. [13][14][15] It is recognized that Nafion is the most widely used electrolyte membrane due to its high mechanical and chemical stability and excellent proton conductivity.…”

A novel SPEEK‐based blends proton exchange membrane doping liquid crystal polymer intercalated montmorillonite (LCT) were prepared by solution casting technology. FT‐IR, XRD and POM proved that SPEEK contained sulfonic acid group and LCT which had liquid crystal intercalated into SPEEK matrix. LCT/SPEEK composite membrane with 1.0 wt% had higher swelling rate and proton conductivity than those membranes. It was also shown that the proton conductivity of LCT/SPEEK composite membrane decreased, but reached 0.137 S/cm when LCT was 1.0 wt%, and the swelling rate of SPEEK membrane was significantly decreased 6.19 % to 3.38 %. The layer silicate structure in LCT promotes its dimensional stability, and the sulfonic group forms hydrogen bond network in SPEEK matrix to promote proton transfer. These results propose the composite membranes as a potential candidate for PEMFC at 25 °C making SPEEK composite membrane.

“…This membrane is chemically and thermally stable, has low resistance and high proton conductivity because the negatively charged hydrophilic sulfonate group attached to the hydrophobic fluorocarbon backbone promotes proton transport. However, new researches have been conducted to replace it due to some limitations and there have been many substitute membrane understudies [21,22]. (Bio)Fouling will deteriorate membrane performance and reduce its durability.…”

“…To solve this, anti-biofilm strategies are implemented [25]. Very recently, Shabani et al [22] have developed a composite polymer electrolytes membrane for microbial fuel cell application by the incorporation of graphene oxide nanosheets in sulfonated polyether ether ketone, and have found higher performance compared with Nafion ® 117 membrane, in terms of power density, voltage, and coulombic efficiency.…”

This article describes for the first time the elaboration of a cationic exchange membrane (CEM) from an end-of-life reverse osmosis (RO) membrane. The cationic exchange membrane has been prepared in two successive steps: (i) chlorine attack and (ii) filtration/adsorption of a polystyrene sulfonic acid (PSS) electrolyte solution. Physicochemical characterizations have been undertaken including (Na + ) transference number (t(Na + )), diffusion flux measurements (J s ), cationic exchange capacity (CEC) determinations, as the properties encountered for a classical cationic exchange membrane. The hydraulic permeability (Lp) was also determined to characterize the molecular weight cutoff. This novel membrane denoted as ANIMMAX has also been characterized by ATR-FTIR and SEM/AFM tools. We have utilized an old brackish water membrane denoted BW30 (stocked in bisulfite 1% for 10 years) to develop a new sulfonated UF membrane with a molecular cutoff of 55 kDa. We have observed that the roughness was divided by 2 (295 to 144nm) showing a lower propensity to fouling/biofouling of the novel membrane elaborated. As for the application, the newly synthesized membrane has been tested during 4 days of experiments in a fungal microbial fuel cell laboratory set-up vs Nafion© 117 the usual cationic membrane in MFC technology. We observed a lower external resistance with a value of 8 kOhm vs 37 kOhm for ANIMMAX vs Nafion ® 117, respectively.
