Abstract

An anode-supported-type solid oxide fuel cell with a proton-conducting electrolyte composed of LaScO3 co-doped with 32.5 mol% Sr and 2 mol% Co was fabricated using a modified pulsed laser deposition (PLD) method. The modified PLD method, which comprised a conventional PLD method combined with an ultrasonically cleaning procedure, enabled deposition at a temperature lower than the cell fabrication temperatures. Thus, this procedure resulted in the deposition of a dense, gas-tight electrolyte of a poorly sinterable material without interaction between the electrode and electrolyte. The fabricated cell functioned in an intermediate temperature range; open circuit voltages and maximum power densities of the cell were 0.89 V and 8.8 mWcm-2 at 700 °C and 0.91 V and 1.9 mWcm-2 at 600 °C.
