Description:

TECHNICAL TOPIC 7 - Fuel Cells
(DE-PS26-05NT42317-07)

Solid-oxide fuel cell (SOFC) technology development seeks to dramatically
reduce the cost of SOFC stacks or increase the efficiency of SOFC power
generation systems. New advances may improve performance, lower system
costs,
shorten development time, take advantage of economies of scale and mass
customization, expand the fuel cell market, exploit the synergy between
fuel
cells and turbines or simplify the balance of plant (BOP).

FutureGen, the Integrated Sequestration and Hydrogen Research Initiative,
is a
$1 billion industry/government partner-ship to design, build and operate a
coal
gasification-based, nearly emission-free coal-fired electricity and
hydrogen
production plant. FutureGen technology goals
(http://www.netl.doe.gov/coal/futuregen/index.html) include the need for
fuel
cell concepts capable of approaching $100/kilowatt stack costs and fuel
cell
system efficiencies approaching 70-80%. The Solid State Energy Conversion
Alliance (SECA) Program goals focus on developing SOFC power generation
system
technology that can be manufactured for $400/kilowatt by 2010. The Fuel
Cell
program has focused on fuel cell stacks, power generation systems, and
fuel

cell-turbine hybrid system concepts.

GENERAL DESCRIPTION OF RESEARCH INTEREST: *For this Topic Area, grant
applications to advance solid oxide fuel cell technology are limited to
the

following:

" Cathode-Interconnect Contact Applications are sought for the research
and
development of material sets and/or methods to provide for the electrical
contact between advanced cathode and interconnect materials under typical
SOFC
operating conditions. Selected materials must be compatible with SOFC
power
systems and materials, and must sustain operating performance for greater
than 40,000
hours
and hundreds of thermal cycles for stationary applications and greater
than 5,000 hours
and
3,000 thermal cycles for transportation systems. Lifetime effects (phase
stability, thermal expansion compatibility, element migration,
conductivity
and
aging) must be addressed and characterized to the extent possible. For
any
new
material set, cost, manufacturability and reliability are critical factors
in
meeting SECA Program goals.

Discussion: Current methods utilize a contact paste to facilitate
electrical
contact between advanced cathode materials (LSM, LSF or LSCF) and the
respective adjoining interconnect materials (e.g., Crofer 22APU, Haynes
230,
etc.). This paste is cured when the stack is first brought to operating
temperature (650 degrees C to 750 degrees C). However, thermo-mechanical
and/or chemical
deterioration of the contact region contributes to excessive degradation
of

SOFC stack electrical performance. Bonding between the cathode and the
interconnect, not just simple normally-loaded contact, is important in
maintaining the electrical contact area and acceptable performance.
Consequently, the selected contact material must be compatible with the
cathode
and interconnect materials with respect to CTE and be able to withstand
the

tensile and shear stresses induced by the differential thermal expansion
resulting from thermal cycling and the in-plane temperature gradients that
exist during steady-state operation. The selected material must be
chemically
stable under high current conditions, buffering interactions between
interconnect oxide and electrode oxide, stable with both and not adversely
affect the formation of the interconnect protective oxide. An
understanding of
relevant degradation mechanisms should be obtained and applied to the
lifetime
performance validation of the contact zone materials configuration. Due
to
the
relatively large thickness of the contact layer, the selected material
must
be
of low resistivity to aid in current collection.

The DOE desires to fund projects that demonstrate in depth understanding
of
the challenges and to maximize utilization/transfer of technology
developed

through this solicitation. Per the HBCU/OMI Program intent discussed in
Section 1.2 of this solicitation, private sector collaboration with solid
oxide
fuel cell system developers is a goal of Technical Topic Area 7 and a
consideration in the evaluation of an application.
