The development of proton-exchange membranes for fuel cells has generated global interest in order to have a potential source of power for stationary and portable applications. The membrane is the heart of a fuel cell and the performance of a fuel cell depends largely on the physico-chemical nature of the membrane and its stability in the hostile environment of hydrogen and oxygen at elevated t...

in the current work, graphene oxide (go) samples were prepared at room temperature from graphite flakes using a modified hummer's method to produce metal-free electrocatalysts. the effect of the duration of the oxidation process on the structural, chemical and physical characteristics of the go samples was evaluated using x-ray diffraction (xrd), fourier transform infrared spectroscopy (ftir), ...

Polymer electrolyte membranes (PEM) and Pt-based catalysts are two crucial components which determine the properties and price of fuel cells. Even though, PEM faces problem of fuel crossover in liquid fuel cells such as direct methanol fuel cell (DMFC) and direct borohydride fuel cell (DBFC), which lowers power output greatly. Here, we report a DBFC in which a polymer fiber membrane (PFM) was u...

In the highly competitive market of fuel cells, solid alkaline fuel cells using liquid fuel (such as cheap, non-toxic and non-valorized glycerol) and not requiring noble metal as catalyst seem quite promising. One of the main hurdles for emergence of such a technology is the development of a hydroxide-conducting membrane characterized by both high conductivity and low fuel permeability. Plasma ...

A proton exchange membrane has been developed for direct methanol fuel cell (DMFC). The nanofiber network composite membranes were prepared by interconnected network of Nafion (perfuorosulfonic acid) nanofibers that have been embedded in an uncharged and inert polymer matrix, by electro-spinning. The spinning solution of Nafion with a low concentration (1 wt% compared to Nafion) of high molecul...

This data provides the fuel cell performance of Nafion based hybrid membranes containing GO and dihydrogen phosphate functionalized ionic liquid (IL) at 70 °C under anhydrous condition. Readers are requested to go through the article entitled "Nafion® based hybrid composite membrane containing GO and dihydrogen phosphate functionalized ionic liquid for high temperature polymer electrolyte membr...

an essential requirement for an operating pem fuel cell is providing proper water content in the membrane. to avoid water flooding an appropriate water balance is required. here, an analytic model of a planar membrane humidifier for pem fuel cell is proposed where the effect of dimensional parameters includes membrane thickness, membrane area and channel hydraulic diameter are investigated. a n...
