In Situ Studies on the Catalytic and Electronic Properties of Multi-Dimensional Cathode

Description: The overall objective of this program was to provide the fundamental background to enable SECA Industrial Team Members to select and develop oxide cathodes for the operation of solid oxide fuel cells in the intermediate temperature (500-700 C). A number of experimental techniques were used to address the specific obstacles within the program. The work expanded our existing experimental techniques to the use of in situ diffraction and spectroscopic techniques that are sensitive to the oxygen and… more

LOW TEMPERATURE CATHODE SUPPORTED ELECTROLYTES

Description: This project has three main goals: Thin Films Studies, Preparation of Graded Porous Substrates and Basic Electrical Characterization and Testing of Planar Single Cells. During this time period substantial progress has been made in developing low temperature deposition techniques to produce dense, nanocrystalline yttrium-stabilized zirconia films on both dense oxide and polymer substrates. Progress has been made in the preparation and characterization of thin electrolytes and porous LSM substrat… more

Microporous and Thin Film Membranes for Solid Oxide Fuel

Description: One of the major limitations to the commercialization of solid oxide fuel cells is the expense of fabricating the required (anode/electrolyte/cathode) cells (currently planar or tubular). The current technology being employed by most of the producers of solid oxide fuel cells is essentially all the same in that it involves standard ceramic processing to make composite structures (either electrolyte or electrode supported). Each investigator/program has their own individual processing steps to p… more

LOW TEMPERATURE CATHODE SUPPORTED ELECTROLYTES

Description: This report represents a summary of the work carried out on this project which started October 1999 and ended March 2003. A list of the publications resulting from the work are contained in Appendix A. The most significant achievements are: (1) Dense nanocrystalline zirconia and ceria films were obtained at temperatures < 400 C. (2) Nanocrystalline films of both ceria and zirconia were characterized. (3) We showed that under anodic conditions 0.5 to 1 micron thick nanocrystalline films of Sc… more

LOW TEMPERATURE CATHODE SUPPORTED ELECTROLYTES

Description: This project has three main goals: Thin Films Studies, Preparation of Graded Porous Substrates and Basic Electrical Characterization and testing of Planar Single Cells. This period has continued to address the problem of making dense 1/2 to 5 {micro}m thick dense layers on porous substrates (the cathode LSM). Our current status is that we are making structures of 2-5 cm{sup 2} in area, which consist of either dense YSZ or CGO infiltrated into a 2-5 {micro}m thick 50% porous layer made of either… more

LOW TEMPERATURE CATHODE SUPPORTED ELECTROLYTES

Description: This project has three main goals: Thin Films Studies, Preparation of Graded Porous Substrates and Basic Electrical Characterization and testing of Planar Single Cells. In this portion of study we have focused on producing YSZ films on porous LSM substrates. When using the polymer precursor there are a number of obstacles to overcome in order to form dense electrolyte layers on porous substrates (cathode or anode). Probably the most difficult problems are: (1) Extreme penetration of the polymer… more

LOW TEMPERATURE CATHODE SUPPORTED ELECTROLYTES

Description: This project has three main goals: Thin Films Studies, Preparation of Graded Porous Substrates and Basic Electrical Characterization and testing of Planar Single Cells. Substantial progress has been made on both characterizing thin films as well as developing methods to produce films on nanoporous substrates. The results of electrical conductivity measurements on ZrO{sub 2}:16%Sc nanocrystalline thin films under controlled oxygen partial pressure and temperature are presented. The experimental … more

Development of a Novel Efficient Solid-Oxide Hybrid for Co-generation of Hydrogen and Electricity Using Nearby Resources for Local Application

Description: Developing safe, reliable, cost-effective, and efficient hydrogen-electricity co-generation systems is an important step in the quest for national energy security and minimized reliance on foreign oil. This project aimed to, through materials research, develop a cost-effective advanced technology cogenerating hydrogen and electricity directly from distributed natural gas and/or coal-derived fuels. This advanced technology was built upon a novel hybrid module composed of solid-oxide fuel-assiste… more
