Importance 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...

Oxidation behavior and electrical Characteristics of used interconnects in solid oxide fuel cells at presence of Mn3O4 and MnFe2O4 coatings

In order to enhance the performance of interconnects which are used in solid oxide fuel cells (SOFCs), a protective/conductive coating can be applied. In this research AISI 430 ferritic stainless steel was coated in a Mn-base pack mixture by pack cementation method. In order to evaluate the oxidation behavior, isothermal oxidation was accomplished for 200 h at 800 ºC. Electrical behavior was al...

Modeling of Solid Oxide Fuel Cells

A comprehensive membrane-electrode assembly (MEA) model of Solid Oxide Fuel Cell (SOFC)s is developed to investigate the effect of various design and operating conditions on the cell performance and to examine the underlying mechanisms that govern their performance. We review and compare the current modeling methodologies, and develop an one-dimensional MEA model based on a comprehensive approa...
