“…However, this type of membrane also exhibits some drawbacks, which are primarily high cost, low stability at high temperatures, low conductivity at low humidity or high temperature and high methanol crossover in direct methanol fuel cells (DMFCs) [2]. Therefore, extensive studies have been focused on developing alternatives to these per fluorosulfonated membranes [3]. In particular, different polymers that adopt the sulfonated aromatic hydrocarbon structure have been tested, including poly(arylene ether sulfone)s [4], poly(ether ether ketone)s [5], poly(sulfide sulfone)s [6], polyimides [7], poly phosphazenes [8] and polybenzimidazoles [9].…”

a b s t r a c tWe describe the synthesis, as well as the electrochemical and structural characterization, of sulfonated polysulfone intended for use in PEM fuel cells. Starting from a commercial polysulfone, we assessed the performance of these prepared ionomers using synthesis protocols compatible with industrial produc tion. The efficiency of the trimethylsilyl chlorosulfonate and chlorosulfonic acid reagents in the sulfo nation process was confirmed by 1 H NMR, FTIR, elemental analysis, chemical titration and thermal analysis (DSC and TGA). Chlorosulfonic acid was the most effective sulfonation reagent. However, based on SEC MALLS, this reagent induced degradation of the backbone that is detrimental to the thermo mechanical stability and lifespan of the membranes. The electrical characterization of the membranes was undertaken using impedance spectroscopy in contact with different HCl aqueous solutions at various temperatures. The activation energies, which ranged from 8.2 to 11 kJ/mol, were in agreement with the prevailing proton vehicular mechanism.

“…Furthermore, although many studies have been conducted to design low cost alternatives to the standard membrane Nafion, which is a perfluorosulfonic acid polymer, this component imposes a severe limitation on fuel cell expansion. [18] Among sustainable alternatives to fossil fuel, proton exchange membrane fuel cells are promising devices that deliver electricity from hydrogen and oxygen, producing only water. The transformation of the fuel and oxidant however relies on raremetal catalysts.…”

Among sustainable alternatives to fossil fuel, proton exchange membrane fuel cells are promising devices that deliver electricity from hydrogen and oxygen, producing only water. The transformation of the fuel and oxidant however relies on rare‐metal catalysts. H2/O2 enzymatic biofuel cells thus emerge as sustainable biotechnological devices in which chemical catalysts are replaced by hydrogenases at the anode and multicopper oxidases at the cathode. This review discusses the recent breakthroughs and the limitations in all the components of H2/O2 biofuel cells: 1) Catalytic mechanisms involved in multicopper oxidases and hydrogenases, in addition to the new potential of enzymes from the biodiversity pool, which exhibit outstanding properties. 2) The molecular basis for oriented enzyme immobilization on the electrochemical interfaces as a prerequisite for a fast direct electron‐transfer rate. 3) The requirement for 3D networks to enhance current densities. 4) The production of H2 from biomass. 5) The history of H2/O2 biofuel cells and recent devices, which also highlights the remaining issues that will allow the use of such devices in low‐power applications.

“…This result exhibits that the higher the ABS content, the lower the permeability value. The lowest permeability was found on chitosan: ABS membrane with mass ratio of 60: 40 and 80: 20 with sulfonation time of 24 hours, which were 3.72785×10 -6 cm 2 4.43692×10 -6 cm 2 /s, respectively. Similar trend was found on chitosan: ABS membrane with the same mass ratio at room temperature sulfonation [20].…”

“…Moreover, membrane is also to separate between anode and cathode side. The most widely used DMFC membrane is the perfluorosulfonic polymers such as Nafion 117 due to its good characteristics of thermal and chemical stability and high proton conductivity [2]. However, perfluorosulfonic membranes suffer some weaknesses.…”

Abstract. Direct Methanol Fuel Cell (DMFC) is fuel cell that converts directly chemical energy in methanol into electrical energy and can be used as a power source for portable electric devices. Compared to Proton Exchange Membrane Fuel Cells (PEMFCs) which use hydrogen as the fuel, DMFC has some advantages, yet methanol-crossover remains a challenge to be solved. In this study, Acrylonitrile Butadiene Styrene (ABS) and chitosan were blended and their characteristics as membrane for DMFC were evaluated. Membranes with variation of chitosan and ABS mass ratio (60:40 and 80:20) and sulfonation time (6, 12, 18, and 24 hours) were prepared and the characteristics such as water uptake, swelling degree, ion exchange capacity and methanol permeability were determined. Both chitosan and ABS mass ratio and time of sulfonation influence the investigated responses. As a result, blended chitosan and ABS is feasible as the DMFC membrane.
