The novel oriented electrospun nanofiber membrane composed of MOFs and SPPESK has been synthesized for proton exchange membrane fuel cell operating at high temperature and anhydrous conditions. It is clear that the oriented nanofiber membrane displays the higher proton conductivity than that of the disordered nanofiber membrane or the membrane prepared by conventional solvent-casting method (wi...

A new system “MSB-AD-V-FC (BEL JAPAN Inc.)” has been developed, which has made it possible to simultaneous measurement of a water vapor adsorption and a proton conductivity to PEM under various experimental conditions (Temp; 353-473K, Humidity;0-95%RH, Press; atmospheric pressure-1.0MPa). The upper mix-conditioned run to PEM enables in a single original chamber considering of both principles of...

A silicotungstic acid (STA) was successfully impregnated onto K10 montmorillonite (MMT) in an effort to improve the properties of SPEEK membrane. Several characterizations such as Fourier transform infrared (FTIR), X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) were carried out in order to confirm the entrapment of STA molecule onto MMT. It was found that the ST...

Tremendous research efforts have been devoted to new methods of water decontamination and splitting at low cost less energy consumption. Herein, we developed a robust electrochemical strategy with an efficient membrane electrode remove refractory organic pollutants simultaneously produce pure hydrogen in wastewater. Firstly, the anode was constructed three-dimensional (3D) nanoneedle array Co3O...

Computational models and simulation tools can provide valuable insight and guidance for design, performance optimization, and cost reduction of fuel cells. In proton-exchange membrane fuel cells it is particularly important to maintain appropriate water content and temperature in the electrolyte membrane. In this paper we describe a mathematical model for the membrane that takes into account th...

In this work membrane (proton exchange membrane) by using the blend polymers (polyethersulfone (PES), Expandable polystyrene (EPS), polyvenylidinefluride polymer (PVDF)) were prepared. This was modified adding organic sulfonic acid to solution precasting process, and sulfonated dipping it in diluted sulfuric (H2SO460%) post casting process. The sulfonation confirmed via FTIR spectra. characteri...

Sulfonic acid-functionalized polymer electrolyte membranes alternative to Nafion(®) were developed. These were hydrocarbon systems, such as blend sulfonated polyetheretherketone (s-PEEK), new generation perfluorosulfonic acid (PFSA) systems, and composite zirconium phosphate-PFSA polymers. The membranes varied in terms of composition, equivalent weight, thickness, and filler and were investigat...

The oxygen reduction reaction (ORR) is an important challenge in the development and large-scale distribution of energy conversion devices, especially low-temperature proton exchange membrane (PEM) fuel cells. In order to speed up ORR kinetics improve cell performance, iron-doped calcium titanate (CTFO) proposed as a cocatalyst. Fundamental physical chemical characterizations by means X-ray dif...

In this paper, a new voltage aging model for the polymer electrolyte membrane fuel cell (PEMFC), which includes multiple degradation mechanisms proton exchange cells, is proposed. The parameters are identified using curve-fitting procedure based on long-term experimental data modular stack under New European Driving Cycle (NEDC). A good fit was found between and data, with R-squared values grea...

A novel bi-layer coating composed of a tantalum base layer with an Indium Tin Oxide (ITO) top was applied to titanium substrates. Samples were polarized ex situ in parameter study, where the pH, potential and temperature electrolyte altered, as well polarization duration. The Interfacial Contact Resistance (ICR) after showed increase time for first 24 h, then stabilized at approx. 30 mΩ cm2. Mi...
