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...

Challenges in computational modeling of two-phase transport in polymer electrolyte fuel cells flow channels: a review
Download2017-01-01
Excess of liquid water in gas channels of polymer electrolyte fuel cells is responsible for malfunctioning of these devices. Not only it decreases their efficiency via partial blockage of reactants and pressure drop, but it can also lead to the irreversible damage due to oxygen starvation in case...
