Abstract

Fuel cells with BaZr0.1Ce0.7Y0.2O3–δ (BZCY) proton-conducting electrolyte is fabricated using spray-modified pressing method. In the present study the spray-modified pressing technology is developed to prepare thin electrolyte layers on porous Ni-BZCY anode supports. SEM data show the BZCY electrolyte film is uniform and dense, well-bonded with the anode substrate. An anode-supported fuel cell with BZCY electrolyte and Ba0.5Sr0.5Co0.8Fe0.2O3–δ (BSCF) cathode is characterized from 600 to 700 °C using hydrogen as fuel and ambient air as oxidant. Maximum power density of 536 mW cm–2 along with a 1.01 V OCV at 700 °C is obtained. Impedance spectra show that Ohmic resistances contribute minor parts to the total ones, for instance, only ~23% when operating at 600 °C. The results demonstrate that spray-modified pressing technology offers a simple and effective way to fabricate quality electrolyte film suitable to operate in intermediate temperature.
