Factors governing oxygen reduction in solid oxide fuel cell cathodes.
Recent worldwide interest in building a decentralized, hydrogen-based energy economy has refocused attention on the solid oxide fuel cell (SOFC) as a potential source of efficient, environmentally friendly, fuel-versatile electric power. Due to its high operating temperature, the SOFC offers several potential advantages over polymer-based fuel cells, including reversible electrode reactions, lo...
متن کاملHybrid 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 کاملMaterials for Solid Oxide Fuel Cells
Solid oxide fuel cells (SOFCs) have the promise to improve energy efficiency and to provide society with a clean energy producing technology. The high temperature of operation (500-1000 C) enables the solid oxide fuel cell to operate with existing fossil fuels and to be efficiently coupled with turbines to give very high efficiency conversion of fuels to electricity. Solid oxide fuel cells are ...
متن کاملImportance of oxygen spillover for fuel oxidation on Ni/YSZ anodes in solid oxide fuel cells.
Using first principles simulations and the Monte Carlo method, the optimal structure of the triple-phase boundaries (TPB) of the Ni/Yttria-Stabilized Zirconia (YSZ) anode in solid oxide fuel cells (SOFCs) is determined. Based on the new TPB microstructures we reveal different reaction pathways for H2 and CO oxidation. In contrast to what was believed in previous theoretical studies, we find tha...
