Integration of a Vanadium Redox Flow Battery with a Proton Exchange Membrane Fuel Cell as an Energy Storage System

The proton exchange membrane (PEM) fuel cell is a green energy producer which converts chemical energy to electricity in high yield. Alternatively, the vanadium redox flow battery (VRB) is one of the best rechargeable batteries because of its capability to average loads and output power sources. These two systems are modeled by Nernst equation and electrochemical rules. An effective energy gene...

Kinetic Modeling of the High Temperature Water Gas Shift Reaction on a Novel Fe-Cr Nanocatalyst by Using Various Kinetic Mechanisms

In this work the kinetic data demanded for kinetic modeling were obtained in temperatures 350, 400, 450 and 500 oC by conducting experimentations on a Fe-Cr nanocatalyst prepared from a novel method and a commercial Fe-Cr-Cu one. The collected data were subjected to kinetic modeling by using two models derived from redox and associative mechanisms as well as an empirical one. The coefficients o...
