Effect of Water Content on Thermodynamic Properties of Compressed Hydrogen (more than 7000 articles reads since April 2021)

This work shows that at low pressure, the presence of water has a large effect on the thermodynamic properties of compressed hydrogen. The conclusions can have consequences for the energetics of a hydrogen refuelling station with electrochemical hydrogen compressors.

Engineering Model for Predicting the Intradiffusion Coefficients of Hydrogen and Oxygen in Vapor, Liquid, and Supercritical Water based on Molecular Dynamics Simulations (more than 3000 articles reads since July 2021)

In this article, a new engineering model that can predict the hydrogen intradiffusivity in vapor, liquid, and supercritical water is presented, along with many new data for the densities, diffusivities, and shear viscosities of the pure hydrogen and of the hydrogen/water mixtures. The new data and the engineering model presented here can be used for the design and optimization of processes encourntered in electrolyzers and fuel cells.
