A Ceramic-Anode Supported Low Temperature Solid Oxide Fuel Cell

Abstract

We report the fabrication and evaluation of a ceramic-anode supported button cell LSCM-SDC/SDC/PBSC (thickness 400 μ m/ 20 μ m/20 μ m). The anode/electrolyte assembly LSCM-SDC/SDC was co-fired at low temperature of 1250 ◦ C, where a slight amount of CuO was mixed with LSCM. The CuO (20.3 wt%) were impregnated into the porous substrate to enhance current collecting effect. The cell exhibited power density of 596 mWcm − 2 and 381 mWcm − 2 at 700 ◦ C with wet hydrogen and methane as the fuel respectively, where the silver paste was used as current collectors, the highest performance up to date for the cells with metal oxide anodes at this temperature.
