Influence of the dwell time in the polarization hysteresis of polymer electrolyte membrane fuel cells
(Elsevier, 2022-07)
The extent of the cell voltage hysteresis observed in polarization curves of PEM fuel cells and the origins causing this effect are investigated by performing experimental polarization curves with different dwell times for ...

New insights into the temperature-water transport-performance relationship in PEM fuel cells
(Elsevier, 2023-04)
Three-dimensional numerical simulations of a single straight-channel PEMFC at three different operating temperatures (343 K, 353 K, and 363 K) and at a relative humidity RH = 90% were carried out, by using potentiostatic ...

Data from Experimental Analysis of the Performance and Load Cycling of a Polymer Electrolyte Membrane Fuel Cell
(MDPI, 2020-05)
Fuel cells are electrochemical devices that convert the chemical energy stored in fuels (hydrogen for polymer electrolyte membrane (PEM) fuel cells) directly into electricity with high e ciency. Fuel cells are already ...
