چکیده

Proton transport property is studied by modelling the intermolecular pair correlation functions of proton ion with electrode and electrolyte a polymer fuel cell (PEMFC) using Materials-Studio then applying molecular dynamics simulation. A stable structure novel design obtained density functional theory. When assumed as anhydrous, efficiency increases. Analysis coordination numbers shows that more protons are found in region oxygen than sulfur atoms Sulfonic acid Ether Ester Ketone~(SEEK) electrolyte. The conductivity values increased including interaction effects from compared to without. At temperature 333 K, these $7.69 \times 10^{5} \hspace{1mm}\mathrm{S \hspace{1mm}cm^{-1}}$ $4.28 \hspace{1mm}cm^{-1}}$, respectively, network hydrogen bond path via processes creating breaking. highest peaks radial distribution function ($g(r)$) calculations appear fall formation region. Thus, it looks combination Pd$\rm_{3}$Ag an unhydrated SEEK could make up for cost effective components new PEMFC.

Dynamics of Autohumidifed PEM Fuel Cell Operation

Start-up and dynamic responses to changes in load are reported for a dry feed, autohumidified polymer electrolyte membrane fuel cell PEMFC . The fuel cell current can be ignited by water injection; criteria are derived for the required water injection as functions of fuel cell size, temperature, and reactant feed rates. Steady-state multiplicity is observed where the fuel cell current can be ei...

Molecular Dynamics Simulation of Water Transportation through Aquaporin-4 in Rat Brain Cells

This paper investigates the mechanism of water transportation through aquaporin-4(AQP4) of ratbrain cells by means of molecular dynamics simulation with CHARMM software. The AQP4 wasembedded into a bilayer made of Dimystroilphosphatylcholine (DMPC). The results illustrate thatwater molecules move through AQP4's channel with change of orientation of oxygen of eachwater molecule.

Molecular Dynamics Simulation of the Melting Process in Au15Ag40 Nanoalloys

In this study the operations of melting of Au15Ag40 nanoalloy have been studied using the molecular dynamic simulations through the Gupta multiparticle potential and the nonergodicity of simulations is eliminated by the multiple histogram method. The melting characteristics are determined by the analysis of variations in the potential energy. The calculations indicate that the melting of Au15Ag...
