Title: High performance metal-supported solid oxide fuel cells with infiltrated electrodes

Abstract

High power density is required to commercialize solid oxide fuel cells for vehicular applications. In this work, high performance of metal supported solid oxide fuel cells (MS-SOFCs) is achieved via catalyst composition, electrode structure, and processing optimization. The full cell configuration consists of a dense ceramic electrolyte and porous ceramic backbones (electrodes) sandwiched between porous stainless steel metal supports. The conventional YSZ electrolyte and backbones are replaced with more conductive and thinner 10Sc1CeSZ ceramics. MS-SOFCs are co-sintered in a single step and subsequently infiltrated with nanocatalysts. Five categories of cathode catalysts are screened in full cells, including: perovskites, nickelates, praseodymium oxide, binary layered composites, and ternary layered composites. Various anode compositions are also tested. The conventional LSM cathode catalyst is replaced with more active Pr ₆O ₁₁ and the Ni content of the SDC-Ni anode is increased. The resulting cells achieve a peak power of 1.56, 2.0, and 2.85 W cm ^-2 at 700, 750, and 800 °C, respectively, with 3%H ₂O/H ₂ as fuel and cathode exposed to air. Multiple cells show reproducible performance (P _max = 1.50 ± 0.06 W cm ^-2) and OCV (1.10 ± 0.02 V). The performance is further increased with cathode exposed to puremore » oxygen (2.0 W cm ^-2 at 700 °C).« less

Ethanol internal reforming in solid oxide fuel cells: A path toward high performance metal-supported cells for vehicular applications

Journal Article Dogdibegovic, Emir ; Fukuyama, Yosuke ; Tucker, Michael C. - Journal of Power Sources

Internal reforming of ethanol fuel was explored on high-performance metal-supported solid oxide fuel cells (MS-SOFCs) with infiltrated catalysts. The hydrogen concentration and internal reforming effects were evaluated systematically with different fuels including: hydrogen, simulated reformate, anhydrous ethanol, ethanol water blend, and hydrogen-nitrogen mixtures. A simple infiltration of Ni reforming catalyst into 40 vol.% Ni-Sm _0.20Ce _0.80O _2-δ (Ni-SDCN ₄₀) and fuel-side metal support leads to complete internal reforming, as validated by comparison to simulated reformate. The performance difference between hydrogen and fully-reformed ethanol is attributed entirely to decrease in hydrogen concentration. High peak power density was achieved for a rangemore »« less

Progress in durability of metal-supported solid oxide fuel cells with infiltrated electrodes

Journal Article Dogdibegovic, Emir ; Wang, Ruofan ; Lau, Grace Y. ; ... - Journal of Power Sources

High power density and longevity are required to commercialize solid oxide fuel cells for vehicular applications. In this work, electrochemical durability of high-performance metal-supported solid oxide fuel cells (MS-SOFCs) with infiltrated catalysts is investigated. Durability screening of various cathode and anode compositions is conducted. The Pr ₆O ₁₁ cathode and SDCN ₄₀ (40 vol% Ni-60 vol% SDC) anode are selected due to preferential tradeoff between performance and durability. X-ray diffraction indicates the catalyst phases are stable after prolonged thermal annealing. Electrochemical impedance and scanning electron microscopy analyses show that the evolution of SDCN40 is minimal, and coarsening and Cr poisoningmore »« less

Performance of Ni/ScSZ cermet anode modified by coating with Gd{sub 0.2}Ce{sub 0.8}O{sub 2} for a SOFC

Journal Article Bo, Huang ; Ye, X F ; Wang, S R ; ... - Materials Research Bulletin

A Ni/scandia-stabilized zirconia (ScSZ) cermet anode was modified by coating with nano-sized gadolinium-doped ceria (GDC, Gd{sub 0.2}Ce{sub 0.8}O{sub 2}) within the pores of the anode for a solid oxide fuel cell (SOFC). X-ray diffraction (XRD) and scanning electron microscopy (SEM) were employed in the anode characterizations. Open circuit voltages (OCVs) increased from 1.027 to 1.078 V, and the maximum power densities increased from 238 to 825 mW/cm{sup 2}, as the operating temperature of a SOFC with 2.0 wt.%GDC-coated Ni/ScSZ anode was increased from 700 to 850 deg. C in humidified hydrogen. The coating of nano-sized Gd{sub 0.2}Ce{sub 0.8}O{sub 2} particlemore »« less

Novel Electrode Materials for Low-Temperature Solid-Oxide Fuel Cells

Technical Report Zha, Shaowu ; Liu, Meilin

Composites electrodes consisting of silver and bismuth vanadates exhibit remarkable catalytic activity for oxygen reduction at 500-550 C and greatly reduce the cathode-electrolyte (doped ceria) resistances of low temperature SOFCs, down to about 0.53 {omega}cm{sup 2} at 500 C and 0.21 {omega}cm{sup 2} at 550 C. The observed power densities of 231, 332, and 443 mWcm-2 at 500, 525 and 550 C, respectively, make it possible to operate SOFCs at temperatures about 500 C. Fuel cell performance depends strongly on the anode microstructure, which is determined by the anode compositions and fabrication conditions. Four types of anodes with two kindsmore »« less

Durability of symmetric-structured metal-supported solid oxide fuel cells

Journal Article Tucker, Michael C. - Journal of Power Sources

Symmetric-structure metal-supported solid oxide fuel cells (MS-SOFC) with YSZ electrolyte are fabricated with porous YSZ backbone electrodes, stainless steel supports, and infiltrated catalysts on both anode and cathode side. Durability towards aggressive thermal and redox cycling, and long-term operation is assessed. Additionally, many sealing material candidates are screened for compatibility with the cell materials and operating conditions, and a commercial sealing glass, GM31107, is selected. LSM/SDCN cells are then subjected to 200 very fast thermal cycles and 20 complete redox cycles, with minimal impact to cell performance. LSM/SDCN and SDCN/SDCN cells are operated for more than 1200 h at 700more »« less
