Characterization and Improvement of Oxygen Mass Transfer in a Rocking Disposable Bioreactor
(University of Waterloo, 2020-06-04)Rocking disposable bioreactors use a cyclic rocking motion to induce mixing and oxygen transfer from the headspace gas into the liquid and are a novel type of bioreactor currently suitable for smaller-scale cell growth. ... -
Impact of Liquid Water on Reactant Mass Transfer in PEM Fuel Cell Electrodes
(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 ... -
In-plane and through-plane gas permeability of carbon fiber electrode backing layers
(Elsevier, 2006-11-08)The absolute gas permeability of several common gas diffusion layer (GDL) materials for polymer electrolyte membrane fuel cells was measured. Measurements were made in three perpendicular directions to investigate anisotropic ... -
Mass Transfer to/from Distributed Sinks/Sources in Porous Media
(University of Waterloo, 2006-12-18)This research addresses a number of fundamental issues concerning convective mass transfer across fluid-fluid interfaces in porous media. Mass transfer to/from distributed sinks/sources is considered for i) the slow ... -
Pore network modeling of fibrous gas diffusion layers for polymer electrolyte membrane fuel cells
(Elsevier, 2007-11-08)A pore network model of the gas diffusion layer (GDL) in a polymer electrolyte membrane fuel cell is developed and validated. The model idealizes the GDL as a regular cubic network of pore bodies and pore throats following ... -
Separation of Phenols and Aniline from Water Streams using Poly(ether-block-amide) Membranes
(University of Waterloo, 2021-10-14)Phenols and aniline are aromatic compounds in which a hydroxyl group and amine group are attached to the benzene ring, respectively. Both are common organic pollutants in a wide range of effluents from such industries as ...
