Quantifying the Role of Cerium Oxide as a Catalyst in Solid Oxide Fuel Cell Anodes
Title of Document: QUANTIFYING THE ROLE OF CERIUM OXIDE AS A CATALYST IN SOLID OXIDE FUEL CELL ANODES Steven C. DeCaluwe, Doctor of Philosophy, 2009 Directed By: Associate Professor Gregory S. Jackson, Department of Mechanical Engineering Solid Oxide Fuel Cells (SOFCs) are an important electrochemical power conversion device, due largely to their high efficiencies and ability to directly oxidiz...
متن کاملMicrofabricated Proton-conducting solid Oxide Fuel cell system
Owing to their high efficiency and energy density, miniaturized fuel cells are an attractive alternative to batteries in the mW-W power generation market for portable consumer and military electronic devices [cf. 1-3]. Hydrogen is being actively considered as a fuel for power generation. It can be supplied either by storage devices or its in-situ generation using reformers. However, safety and ...
متن کاملRedox Stable Anodes for Solid Oxide Fuel Cells
*Correspondence: Fanglin Chen, Department of Mechanical Engineering, University of South Carolina, 300 Main Street, Columbia, SC 29208, USA e-mail: [email protected] Solid oxide fuel cells (SOFCs) can convert chemical energy from the fuel directly to electrical energy with high efficiency and fuel flexibility. Ni-based cermets have been the most widely adopted anode for SOFCs. However, the conv...
متن کاملPercolation Theory in Solid Oxide Fuel Cell Composite Electrodes with a Mixed Electronic and Ionic Conductor
Percolation theory is generalized to predict the effective properties of specific solid oxide fuel cell composite electrodes, which consist of a pure ion conducting material (e.g., YSZ or GDC) and a mixed electron and ion conducting material (e.g., LSCF, LSCM or CeO2). The investigated properties include the probabilities of an LSCF particle belonging to the electron and ion conducting paths, p...
متن کاملAn 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...
