Hybrid Molten/Solid In2O3-Bi2O3 Oxygen Ion Transport Membranes
The hybrid molten/solid In2O3 - 30-48 wt.% Bi2O3 oxide materials were studied with respect to their transport properties. The conductivities, oxygen ion transport numbers and oxygen permeation fluxes have been measured by using the four-probe DC, volumetric measurements of the faradaic efficiency and gas flow techniques, respectively. We show that the...
متن کاملEvidence and Model for Strain-Driven Release of Metal Nanocatalysts from Perovskites during Exsolution.
The evolution of the surface morphology during exsolution of Ni from the perovskite La0.4Sr0.4Ti0.97Ni0.03O3-δ under reducing conditions was determined using atomic force microscopy. The exsolution process was found to initially induce the formation of a 20-30 nm deep pit on the oxide surface followed by the emergence of a Ni particle at the bottom of the pit. Continued emergence of the particl...
متن کاملControlling the Mechanical and Transport Properties of Layer-by-Layer Films and Electrospun Mat Composite Membranes for Fuel Cell Applications
There is an ever increasing need for clean, portable energy devices, such as fuel cells and high energy batteries to replace or reduce the world’s dependence on fossil fuels. The continued development of thin-film solid polymer electrolytes with improved mechanical and ion transport properties is critical for the further advancement of such electrochemical energy devices. For hydrogen and metha...
متن کاملMechanical and transport properties of layer-by-layer electrospun composite proton exchange membranes for fuel cell applications.
Composite membranes composed of highly conductive and selective layer-by-layer (LbL) films and electrospun fiber mats were fabricated and characterized for mechanical strength and electrochemical selectivity. The LbL component consists of a proton-conducting, methanol-blocking poly(diallyl dimethyl ammonium chloride)/sulfonated poly(2,6-dimethyl-1,4-phenylene oxide) (PDAC/sPPO) thin film. The e...
