Proton exchange membrane fuel cells (PEMFC) are widely used in transportation systems owing to their desirable characteristics such as high efficacy and low operating temperature. However, the cell exhibit load changes well voltage power losses so reduce dependence on battery. The aim of present study was explore composition basic working principle PEMFC. A PEMFC electrochemical reaction model ...

A three dimensional (3D), gas-liquid multi-phase flow and transport model in COMSOL Multiphysics has been developed to simulate phenomena a proton exchange membrane fuel cell (PEMFC) with several operational parameters. The effects of changes oxygen hydrogen input velocities on concentration change at electrodes, current density polymeric performance have investigated PEMFC. simulations, made f...

Governments and private investors are becoming aware of the problems derived from the energy dependency on fossil fuels and other non-renewable energies. In this context, proton exchange membrane fuel cells (PEMFC), which use hydrogen as fuel, are gaining increasing attention as clean and efficient energy conversion devices for a broad range of applications, such as automotive, stationary combi...

This paper presents a novel adaptive scheme for energy management in stand-alone hybrid power systems. The proposed management system is designed to manage the power flow between the hybrid power system and energy storage elements in order to satisfy the load requirements based on artificial neural network (ANN) and fuzzy logic controllers. The neural network controller is employed to achieve t...

One of the most important parts of a polymer electrolyte membrane fuel cell (PEMFC) is the membrane electrode assembly (MEA). However, the delamination between the membrane and electrode layers, induced by uneven distribution of internal stress and stress concentration due to the inconsistent water and thermal expansion properties, greatly reduces the PEMFC durability. Based on the data from th...
