Abstract

The purpose of this research is to improve the properties of the current state-of-the-art materials used for solid oxide fuel cells (SOFCs). The objectives are to: (1) develop materials based on modifications of the state-of-the-art materials; (2) minimize or eliminate stability problems in the cathode, anode, and interconnect; (3) Electrochemically evaluate (in reproducible and controlled laboratory tests) the current state-of-the-art air electrode materials and cathode/electrolyte interfacial properties; (4) Develop accelerated electrochemical test methods to evaluate the performance of SOFCs under controlled and reproducible conditions; and (5) Develop and test materials for use in low-temperature SOFCs.

Alternative materials for solid oxide fuel cells: Processing and interactions of materials

Technical Report Bates, J; Armstrong, T; Chick, L

The purpose of this research is to develop alternative materials for solid oxide fuel cell (SOFC) interconnections and electrodes with improved electrical, thermal, and electrochemical properties. The overall approach for this research and development is to: minimize the number of cations in the electrode, electrolyte, and interconnection by developing yttrium compounds, such as Y(Ca)CrO{sub 3} as the interconnection, and Y(M{prime})MnO{sub 3} as the air electrode; develop advanced synthesis and fabrication processes for air sintering, below 1,500 C, of chromite interconnections through (1) the use of sintering aids; and (2) the synthesis of submicrometer powders; establish methods for the simultaneous processingmore »« less

Advanced materials for solid oxide fuel cells. [In/sub 2/O/sub 3/-PrO/sub 1. 83/-ZrO/sub 2/]

Conference Griffin, C; Bates, J

Materials based on the In/sub 2/O/sub 3/-PrO/sub 1.83/-ZrO/sub 2/ system were examined as potential electrodes and current interconnects for solid oxide fuel cells (SOFC). The electrical transport, thermal, and electrochemical properties are described in relationship to structure, phase equilibria, and composition. The electrical conductivity was dependent on structure and composition, and can exceed the conductivity of the state-of-the-art electrode/interconnect materials. The instability of the In/sub 2/O/sub 3/ in reducing environments may eliminate this system as SOFC anodes or interconnects. This system may be used as cathodes if indium does not diffuse into the electrolyte and degrade fuel cell performance. 4more » refs., 8 figs., 4 tabs.« less
Solid Oxide Fuel Cells

Journal Article Yang, Z; Stevenson, Jeffry; Singh, Prabhakar - Advanced Materials & Processes, 161(6):34-37

Solid oxide fuel cell (SOFC) technology, which offers many advantages over traditional energy conversion systems including low emission and high efficiency, has become increasingly attractive to the utility, automotive, and defense industries (as shown in Figure 1). As an all solid-state energy conversion device, the SOFC operates at high temperatures (700-1,000 C) and produces electricity by electrochemically combining the fuel and oxidant gases across an ionically conducting oxide membrane. To build up a useful voltage, a number of cells or PENs (Positive cathode-Electrolyte-Negative anode) are electrically connected in series in a stack through bi-polar plates, also known as interconnects.

Yttria-stabilized zirconia solid oxide electrolyte fuel cells--- monolithic solid oxide fuel cells

Technical Report

The monolithic solid oxide fuel cell (MSOFC) is currently under development for a variety of applications including coal-based power generation. The MSOFC is a design concept that places the thin components of a solid oxide fuel cell in lightweight, compact, corrugated structure, and so achieves high efficiency and excellent performance simultaneously with high power density. The MSOFC can be integrated with coal gasification plants and is expected to have high overall efficiency in the conversion of the chemical energy of coal to electrical energy. This report describes work aimed at (1) assessing manufacturing costs for the MSOFC and system costsmore »« less
