Mass transport in PEM water electrolysers: A review

Advanced Construction Materials for High Temperature Steam PEM Electrolysers

A Critical Review of Water Transport Models in Gas Diffusion Media of Pem Fuel Cell

Proton Exchange Membrane (PEM) fuel cells are gaining popularity as a replacement to the internal combustion engine in automobiles. This application will demand high levels of performance from the fuel cell making it critical that proper water management is maintained. One of the areas of interest in water management is the transport of water through the Gas Diffusion Medium (GDM) on the cathod...

Effect of Water Transport on the Production of Hydrogen and Sulfuric Acid in a PEM Electrolyzer

The thermochemical cycle involving the interconversion between sulfur dioxide and sulfuric acid is a promising method for efficient, large-scale production of hydrogen. A key step in the process is the oxidation of sulfur dioxide to sulfuric acid in an electrolyzer. Gaseous SO2 fed to a proton exchange membrane PEM electrolyzer was previously investigated and was shown to be a promising system ...

Sperm Transport in the Mare Reproductive Tract: A Review

The objective of this study was to review the literature on sperm transport in the mare. During this process the sperm cells must reach the oviducts in order to fertilize the oocyte, but before reaching this site it must go through the uterus that is a hostile environment at this moment since there is an inflammatory reaction in this location that aims to eliminate excess spermatozoa and bacter...

Computational Simulation of Water Transport in Pem Fuel Cells Using an Improved Membrane Model

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...
