Study on water and oxygen transfer characteristics of HT-PEM fuel cells
Heliyon, 2023 In this study, a steady-state model is developed by combining mechanical, Navier–Stokes, Maxwell–Stefan, and Butler–Volmer equations. This model is then used to investigate the influences of diffusion layer thickness deformation under a specific assembly

Nanotomography based study of gas diffusion layers [PDF]
Microelectronic Engineering, 2010 Nano-computed tomography (nanoCT) was used for non-invasive 3D visualization and characterization of porous gas diffusion layer (GDL) for polymer electrolyte membrane fuel cells (PEMFC). The study was conducted using reconstruction of 3D images of a GDL of polymer electrolyte fuel cell to determine the critical nanostructural parameters of the layer ...

Apparent Permeability Model for Shale Gas Reservoirs Considering Multiple Transport Mechanisms
Geofluids, 2018 Shale formation is featured in nanopores and much gas adsorptions. Gas flow in the shale matrix is not a singular viscous flow, but a combination of multiple mechanisms. Much work has been carried out to analyze apparent permeability of shale, but little

Effect of seasoning-layer stress on fluorine diffusion
AIP Advances, 2020 In semiconductor thin-film deposition equipment in which a fluorine- or chlorine-based gas is used as a cleaning gas, reducing residual fluorine or chlorine inside the equipment is important for increasing production efficiency and reducing production ...

Kinetic multi-layer model of aerosol surface and bulk chemistry (KM-SUB): the influence of interfacial transport and bulk diffusion on the oxidation of oleic acid by ozone [PDF]
, 2010 We present a novel kinetic multi-layer model that explicitly resolves mass transport and chemical reaction at the surface and in the bulk of aerosol particles (KM-SUB). The model is based on the PRA framework of gas–particle interactions (P¨oschl et al.

Effect of H2 on the microstructure and properties of TiO2 films grown by atmospheric pressure MOCVD on steel substrates [PDF]
, 2009 TiO2 thin films were deposited under atmospheric pressure by MOCVD in the range 400-600 °C on various steel substrates under hydrogen ambiance. It is unusual to study the growth of functional oxide layers under H2 partial pressure, i.e.
