A MIXED WETTABILITY PORE SIZE DISTRIBUTION MODEL FOR THE ANALYSIS OF WATER TRANSPORT IN PEMFC MATERIALS
DownloadFall 2013
Mateo Villanueva, Pedro Abdiel
Water management on proton exchange membrane fuel cells is one of the biggest issues that stop the effective commercialization of this promising technology. Due to water flooding, the performance of fuel cells decays rapidly at high current densities. To better design fuel cell electrodes, a...

Characterizing Dual-wettability Pore Network of Unconventional Rocks by Analyzing Water and Oil Imbibition Data
DownloadSpring 2018
Recent studies show that the pore network of unconventional rocks generally consists of inorganic and organic parts. The organic part has high wetting affinity towards the oleic phase but low wetting affinity towards the aqueous phase. In contrast, the inorganic part has high wetting affinity...

Estimation of relative transport properties of fuel cell and electrolyzer transport layers by pore network and continuum based direct simulations
DownloadSpring 2020
Improvements in the imaging techniques have enabled the capturing of images with high resolution, thereby permitting the reconstruction of complex porous media that can be analyzed by computer simulations. The two most popular methods for numerically analyzing transport in porous media are pore...

Hydrocarbon Adsorption Characteristics and Absolute Adsorption Estimation in Shale Nanoporous Media from Statistical Thermodynamics Approaches
DownloadFall 2021
Shale gas has become a very important unconventional energy resource and significantly increased the global energy supply. Due to the presence of large amount of specific surface area and nanopores in shale rock, the phenomenon of gas molecules accumulation on the solid surface is the so-called...
