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...

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...
