“…The properties mainly include proton conductivity, methanol permeability and mechanical property were affected by size of GO nanosheets. It is worth to note that the SPI-0.5 %-GO composite membrane with the smallest size GO showed the best and outstanding fuel cell performance compared to that of pure SPI and other SPI-GO composite membranes [50].…”

“…An extremely high proton conductivity membrane was obtained by incorporated graphene oxide (GO) into sulfonated polyimide (SPI) where the proton conductivity was 1.2 S/cm at 80˝C and 100% RH. This can be attributed to the formation of strong hydrogen bonding interactions between the small GO and SPI, resulting in a well-defined microstructure and well-connected proton transport channels being formed [44].…”

Fuel cells are the most clean and efficient power source for vehicles. In particular, proton exchange membrane fuel cells (PEMFCs) are the most promising candidate for automobile applications due to their rapid start-up and low-temperature operation. Through extensive global research efforts in the latest decade, the performance of PEMFCs, including energy efficiency, volumetric and mass power density, and low temperature startup ability, have achieved significant breakthroughs. In 2014, fuel cell powered vehicles were introduced into the market by several prominent vehicle companies. However, the low durability and high cost of PEMFC systems are still the main obstacles for large-scale industrialization of this technology. The key materials and components used in PEMFCs greatly affect their durability and cost. In this review, the technical progress of key materials and components for PEMFCs has been summarized and critically discussed, including topics such as the membrane, catalyst layer, gas diffusion layer, and bipolar plate. The development of high-durability processing technologies is also introduced. Finally, this review is concluded with personal perspectives on the future research directions of this area.

“…To improve the effectiveness of fuel cell membranes and to reduce production costs, some hydrocarbon membranes have been developed, including polyether sulfone [4], polyether ether ketone [5], polyimide [6], acrylonitrile butadiene styrene (ABS) [7][8][9]. Membranes from this aliphatic or aromatic polymer group have advantages, such as cheap price, commercially available, and the structure that are capable of storing moisture hence they can operate at higher temperature than Nafion.…”

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.
