Direct measurement of the capillary pressure characteristics of water-air-gas diffusion layer systems for PEM fuel cells
Gostick, Jeffrey Thomas; Ioannidis, Marios A.; Fowler, Michael W.; Pritzker, Mark D. (Elsevier, 2008-10-01)A method and apparatus for measuring the relationship between air-water capillary pressure and water saturation in PEMFC gas diffusion layers is described. Capillary pressure data for water injection and withdrawal from ... -
Electrodeposition and electrodissolution of zinc in mixed methanesulfonate-based electrolytes
Amini, Kiana; Pritzker, Mark D. (Elsevier, 2018-04-01)Zinc electrodeposition and electrodissolution in methanesulfonic acid (MSA) electrolytes mixed with chloride or sulfate are investigated in a 3-electrode cell for eventual use in divided and undivided zinc-cerium redox ... -
Impact of Liquid Water on Reactant Mass Transfer in PEM Fuel Cell Electrodes
Gostick, Jeffrey Thomas; Ioannidis, Marios A.; Pritzker, Mark D.; Fowler, Michael W. (Electrochemical Society, 2010)The breakthrough conditions (capillary pressure and liquid water saturation) in a fibrous gas diffusion medium (GDM) used in polymer electrolyte membrane (PEM) fuel cell electrodes have been studied experimentally by two ... -
