Title: Protective Ceramic Coatings for Solid Oxide Fuel Cell (SOFC) Balance-of-Plant Components

Abstract

Solid oxide fuel cells (SOFCs) have the potential to meet the growing need for electrical power generation if the cost per megawatt can be further reduced. Currently, SOFC stacks are replaced too frequently to be cost competitive. SOFC service life can be extended by preventing chromium- (Cr-) bearing species from evaporating from the interior surfaces of balance of plant (BOP) components and poisoning the cathode to increase the lifetime. We have developed yttria-stabilized zirconia (YSZ) and aluminum oxide- (Al ₂ O ₃ -) modified sol-gel paints or inks for coating BOP components. 430 stainless steel (430SS) substrates with three surface conditions were coated with the 0.8–1.5 µ m thick YSZ and Al ₂ O ₃ paints. The coated 430SS samples were tested for thermal cycling resistance, thermal soak, and Cr evaporation. Thermal soak and thermal cycling test results show promise for the YSZ-coated 430SS substrates. The Cr evaporation test of a coated substrate showed a 51% reduction in Cr generation, when compared with a bare substrate.

Cost-Reducing Methods for Thin Film Solid Oxide Fuel Cells

Journal Article Glass, R S - Materials Research Society Bulletin

Lawrence Livermore National Laboratory (LLNL) has developed an improved method for fabrication of a thin film Solid Oxide Fuel Cell (SOFC) using a colloidal technique. Dense, crack-free, yttria-stabilized-zirconia (YSZ) films of up to 100 microns thick were deposited on nickel oxide/YSZ substrates and porous La{sub 0.85}Sr{sub 0.15}MnO{sub 3} (LSM) substrates. The new technique was also used to deposit a compositionally-graded film of YSZ and Ce{sub 0.8}Y{sub 0.2}O{sub 2} (CYO), which is useful for matching the thermal expansion coefficient to an adjacent layer. The SOFC is a solid-state electrochemical device that converts the chemical energy of fuel directly into electricity. Itsmore »« less

Tailoring Fe-Base Alloys for Intermediate Temperature SOFC Interconnect Application

Technical Report Zhu, J H ; Brady, M P ; Anderson, H U

This report summarized the research efforts and major conclusions for our SECA Phase I and II project focused on Cr-free or low Cr Fe-Ni based alloy development for intermediate temperature solid oxide fuel cell (SOFC) interconnect application. Electrical conductivity measurement on bulk (Fe,Ni){sub 3}O{sub 4} coupons indicated that this spinel phase possessed a higher electrical conductivity than Cr{sub 1.5}Mn{sub 1.5}O{sub 4} spinel and Cr{sub 2}O{sub 3}, which was consistent with the low area specific resistance (ASR) of the oxide scale formed on these Fe-Ni based alloys. For Cr-free Fe-Ni binary alloys, although the increase in Ni content in the alloysmore »« less

Durable, Impermeable Brazes for Solid Oxide Fuel Cells (Final Report)

Technical Report Nicholas, Jason D. ; Qi, Yue ; Bieler, Thomas R.

To develop a new braze to replace the current state-of-the-art Ag-CuO reactive air braze (RAB), two approaches were proposed: 1) development of a new, self-passivating, silver-free braze and 2) development of a CuO-free, silver-based braze. For the first approach, an integrated computational-experimental method was used. Thermo-Calc® was utilized to quickly screen through hundreds of alloy systems to identify candidate braze compositions with the appropriate melting ranges. Material compositions, melting ranges, mechanical properties, oxidation resistance, and wetting characteristics of the candidate alloys were then analyzed experimentally. Substrate surface pre-treatments, active element additions, and novel brazing schemes were also investigated. Unfortunately, themore »« less

Surface Scale Formation on SOFC Proximal Balance of Plant Components

Conference Gerdes, K R ; Johnson, C

The efficiency and performance of solid oxide fuel cells (SOFC) are known to degrade when chromium species are present at the cathode/electrolyte interface. Chromium containing alloys generate volatile chrome species that deposit as Cr2O3(s) under modest current densities (~0.5 A/cm2). Volatilization of chrome species from SOFC proximal balance of plant (BoP) components has received little attention. These components can reach temperatures of 600-800°C through direct thermal contact with the hot cell stack. Simple calculations show that a BoP chromium source can generate enough chromium to affect the power output of a 25-Watt cell in less than 50 hours of operation.more »« less
Minimizing Cr-Evaporation from Balance Of Plant Components By Utilizing Cost-Effective Alumina-Forming Austenitic Steels

Technical Report Liu, Xingbo ; Michael, Brady

A solid oxide fuel cell (SOFC) is a clean and efficient energy conversion device. The development of intermediate-temperature SOFCs has made it preferable to use metallic interconnects (MICs) to greatly reduce the cost and significantly increase the efficiency compared to ceramic interconnect materials. However, gaseous chromium species will evaporate from the chromium-containing layer formed on the surface of commonly used MICs and balance of plant (BoP) components. Volatile chromium species have been shown to form solid deposits which poison the cathodes of SOFCs, causing drastic cell performance degradation and thereby limiting commercialization. In order to alleviate the Cr poisoning andmore »« less
