Propane Fueled Solid Oxide Fuel Cells

An octane-fueled solid oxide fuel cell.

There are substantial barriers to the introduction of hydrogen fuel cells for transportation, including the high cost of fuel-cell systems, the current lack of a hydrogen infrastructure, and the relatively low fuel efficiency when using hydrogen produced from hydrocarbons. Here, we describe a solid oxide fuel cell that combines a catalyst layer with a conventional anode, allowing internal refor...

Modeling of Proton-Conducting Solid Oxide Fuel Cells Fueled with Syngas

Solid oxide fuel cells (SOFCs) with proton conducting electrolyte (H-SOFCs) are promising power sources for stationary applications. Compared with other types of fuel cells, one distinct feature of SOFC is their fuel flexibility. In this study, a 2D model is developed to investigate the transport and reaction in an H-SOFC fueled with syngas, which can be produced from conventional natural gas o...

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...
