Solid
oxide fuel cell (SOFC) systems that operate at lower temperatures are currently
receiving considerable attention. There
are very strong manufacturing and operating – hence economic –driving forces
to get to so-called intermediate temperatures (550-800°C). One
of the major impediments in the development of intermediate temperature SOFCs is
the lack of an anode material that can operate in natural gas without suffering
from carbon build up due to catalytic cracking.
This project will demonstrate a Combustion Chemical Vapor Deposition (CCVD)
process to fabricate Cu-samaria-doped ceria cermet anodes for intermediate
temperature SOFCs in a single step process that is amenable to continuous
production. Phase I will demonstrate
the viability of CCVD to produce high surface area and controlled porosity
Cu-(Ce0.8Sm0.2)O1.9 (Cu-SDC) and Sr0.5Sm0.5CoO3 (SSC) on a SDC electrolyte with
power density higher than 400 mW/cm² at 600°C. A
materials characterization will be carried out and electrochemical measurements
will be performed.
Commercial
Applications and Other Benefits
as described by the awardee: The new
anode material should result in a low-cost fuel cell technology that, when used
for power generation purposes, could potentially achieve at least three times
greater fuel economy than conventional sources of energy (i.e. fossil fuels)
with significantly reduced emissions.
