Low-Melting CaCl2-NaCl-Al2O3 Electrolyte for Direct Electrochemical Reduction Solid Al2O3

Low-Melting CaCl2-NaCl-Al2O3 Electrolyte for Direct Electrochemical Reduction Solid Al2O3

The electrical conductivity and density of the low-melting CaCl2-NaCl-Al2O3 systems at 550°C~800°C ranges were respectively measured by the Continuously Varying Cell Constant Technique, ac-techniques and Archimedes method. The materials were applied as the electrolyte for the direct electrochemical reduction solid Al2O3 at 550°C ~800°C. The materials were composed of 71wt.%~87wt.%CaCl2 (corresp...

Polystyrene-Al2O3 composite solid polymer electrolyte for lithium secondary battery

In a common salt-in-polymer electrolyte, a polymer which has polar groups in the molecular chain is necessary because the polar groups dissolve lithium salt and coordinate cations. Based on the above point of view, polystyrene [PS] that has nonpolar groups is not suitable for the polymer matrix. However, in this PS-based composite polymer-in-salt system, the transport of cations is not by segme...

Al2O3 Disk Supported Si3N4 Hydrogen Purification Membrane for Low Temperature Polymer Electrolyte Membrane Fuel Cells

Reformate gas, a commonly employed fuel for polymer electrolyte membrane fuel cells (PEMFCs), contains carbon monoxide, which poisons Pt-containing anodes in such devices. A novel, low-cost mesoporous Si3N4 selective gas separation material was tested as a hydrogen clean-up membrane to remove CO from simulated feed gas to single-cell PEMFC, employing Nafion as the polymer electrolyte membrane. ...
