Nafion/graphene oxide composite membranes for low humidifying polymer electrolyte membrane fuel cell

Enhancement of PEM fuel cell performance at higher temperatures and lower humidities by high performance membrane electrode assembly based on Nafion/zeolite membrane

“…However, the Nafion membranes also have several disadvantages such as a decrease in the ionic conductivity and low humidity at high temperatures, which is a barrier for commercialization. Since the water content in the proton exchange membrane is critical, the external humidification of the reactant gases normally has been applied to practical PEMFC systems [5]. However, the external humidification makes the size of the fuel cell system large and that causes burden of portability.…”

Self-humidifying Pt–graphene/SiO2 composite membrane for polymer electrolyte membrane fuel cell

“…Most recently, Lee et al [37] reported Nafion/graphene oxide (GO) composite membrane for self-humidifying PEMFC. As of now, however, no Nafion/Pt-graphene/SiO 2 composite membrane has been reported for self-humidifying PEMFC.…”

Graphene oxide-modified ZnO particles: synthesis, characterization, and antibacterial properties

“…27 Graphite powder (2 g) was dissolved in 30 mL sulfuric acid (98%, mass percent) under strong stirring for 1 hour. Potassium permanganate (6 g) was added gradually with stirring, and the solution was kept at 35°C in an ice bath for 1 hour.…”

“…[23][24][25] In this study, we examined the antibacterial properties of ZnO/graphene oxide composites with a microdilution method and live/ dead assay. 12,[26][27] The experimental results showed minimum inhibitory concentrations (MICs) of 6.25 µg/mL for Escherichia coli and Salmonella typhimurium, 12.5 µg/mL for Bacillus subtilis, and 25 µg/mL for Enterococcus faecalis.…”
