Analyzing Multiphase Flow in Membrane Electrode Assembly Using a Mixed Wettability Mathematical Model
DownloadFall 2018
Improving fuel cell performance at high current density is critical for reducing stack size, cost and weight in automobile applications. A major source of performance losses at high current density is the accumulation of liquid water in the electrode which blocks reactant transport. Studying...

Characterization of Water Transport and Liquid Accumulation in Proton Exchange Membrane Fuel Cells
DownloadSpring 2024
Hydrogen proton exchange membrane fuel cell (PEMFC) vehicles present a viable solution for decarbonizing the heavy-duty and long-distance transportation sector. They convert the chemical energy of hydrogen directly into electricity, with the only by-products being heat and water and, therefore,...
