Operando XAFS Analysis of Solid Oxide Fuel Cells (SOFCs)

Operando X-ray Investigation of Electrode/Electrolyte Interfaces in Model Solid Oxide Fuel Cells

We employed operando anomalous surface X-ray diffraction to investigate the buried interface between the cathode and the electrolyte of a model solid oxide fuel cell with atomic resolution. The cell was studied under different oxygen pressures at elevated temperatures and polarizations by external potential control. Making use of anomalous X-ray diffraction effects at the Y and Zr K-edges allow...

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...

Modeling of Solid-Oxide Fuel Cells

This article presents a brief review on modeling philosophies of solid-oxide fuel cells (SOFCs) including an introduction to SOFC components and their functions. While a plethora of numerical models is available for SOFC modeling and simulation, this paper focuses on a general overview on mathematical model equations that represent the physico-chemical processes occurring in SOFCs and their bou...

Direct hydrocarbon solid oxide fuel cells.

Solid Oxide Fuel Cells for Transportation

The well-known compatibility of the SOFC with hydrocarbon fuels makes the solid oxide fuel cell a strong contender for transportation applications. Gasoline and diesel will continue to be the dominant fuels for decades to come. The 500 million automobiles, the existing fuel distribution system and the economic power of oil and automobile companies combined form a strong inertia in favour of liq...
