Low Temperature Preparation and Characterization of Solid Oxide Fuel Cells on FeCr-Based Alloy Support by Aerosol Deposition |
| 초록 |
Metal-supported solid oxide fuel cells were fabricated using room-temperature operating aerosol deposition consisting of a co-fired FeCr-based alloy support, La0.2Sr0.8TiO3 diffusion barrier, Ni-Gd0.1Ce0.9O2-δ anode, aerosol-deposited dense Y0.16Zr0.84O2-δ electrolyte, and aerosol-deposited porous (La0.6Sr0.4)(Co0.2Fe0.8)O3-δ. The La0.2Sr0.8TiO3 diffusion barrier effectively suppressed the reaction between the FeCr based alloy support and Ni in the anode during co-firing at 1300oC. Room-temperature deposition of the electrolyte and cathode layers in low vacuum conditions can effectively prevent metal support degradation and cathode decomposition. Microstructural analysis of the anode, electrolyte, and cathode layers is presented. An open circuit voltage of 1.08V and maximum power density of 0.71 W/cm2 were achieved at 750oC. |
