... cell, it will make the surface temperature of the membrane too high and increase the evaporation of water. Low water content reduces the conductivity of the membrane. When the membrane is severely dehydrated, the service life of the membrane will be shortened [ 10 ]. One of the effective methods...

... and load changes, to accurately capture the water content in the membrane with changes in cell voltage. The water content obtained through CFD simulations is, in turn, used to carry out two-dimensional (2D) finite element (FE) analysis to predict the mechanical response of the membrane undergoing cyclic...

... fuel cells (PEMFCs). Effects on the current density, temperature difference, and water content have been simulated and analyzed, respectively, with conventional and interdigitated flow field when the humidification in the anode or cathode is from 25% to 100%, respectively. The numerical results show...

... of 10% dda have a difference of about 5% water content. Chitosan membranes with a lower dda were found to have higher water content resulting in lower membrane resistances to proton flow. The water content of chitosan membranes was higher than Nafion membranes. The average resistance to proton flow...

... transport equations and available material properties from the literature are translated into a single-cell fuel cell model, which is implemented using the object modeling technique. The PEFC model is applied to predict and validate the net water transport ratio and water content under a range of operating...
