Development of scalable, low cost, and high
yield processes for aerosol deposition for anodes, cathode, and electrolyte
materials on planar and tubular electrode supported SOFC designs.
The key benefit is that the process is tailorable to accommodate the wide range
of characteristics for current and future designs and materials. These
characteristics include porosity and shrinkage of the support along with desired
porosity of the sintered coatings.
Continuous Process for Low Cost, High Quality YSZ Powder
Process development aimed at fabricating
high performance yttria stabilized zirconia to meet industrial process
specifications. Research has identified tailorable, low cost, and scalable
processing routes at the pilot plant level that lead to YSZ materials with good
electrochemical performance and reduced sintering temperature. These
improvements will assist SECA members and other developers pursuing both
cathode- and anode-supported SOFC designs. These materials are available on a limited basis
to development partners. Please inquire for more information.
Low Temperature Cathode Materials for SOFCs
Through investigations of A and B site
doping in perovskite materials, NexTech has
reduced cathode-electrolyte interfacial resistance in SOFC operating below
750°C. These materials are available on a limited basis to our growing number of
development partners.
Highly Textured Composite Seals for SOFC Application
The goal of this project is to develop
composite seal materials for intermediate temperature SOFC stacks. Ceramic-glass
composites are being evaluated for mechanical compliance and seal quality under
temperature cycling conditions. University of Missouri-Rolla is a partner on
this project. |
