摘要：
An electrolyte supported intermediate temperature SOFC (IT-SOFC) using 15 mol% Y-doped BaZrO3 (BZY15) is fabricated and tested in the temperature range from 550 degrees C to 650 degrees C to study fundamental properties of an IT-SOFC using proton conductors. The measurement of I-V characteristics and impedance spectra reveal that BZY15 is superior to oxygen ionic conductors as an electrolyte material from the viewpoint of electrolyte resistance in the tested temperature range. The results also confirm the necessity of reducing cathodic overpotential.
