Dependence of power density on anode functional layer thickness in anode-supported solid oxide fuel cells

To study the geometrical scale dependency of thin film solid oxide fuel cells (SOFCs), we fabricated three thin films SOFCs which have the same cross-sectional structure but different electrode areas of 1 mm2, 4 mm2 and 9 mm2. Since the activation and ohmic losses of SOFCs depend on their active region, we examined the variations of the power density of the cells with a Pt/YSZ/Pt structure and simulated the power density variations using the COMSOL software package.

SrFe0.9Al0.1O3-δ(SFA) powder was mixed with a different mass content of SDC 10, 20 and 30 wt.% to form SFA-SDC composite cathodes subsequently investigated as potential IT-SOFC cathodes on LSGM electrolytes. No obvious reaction products between SDC (or LSGM) and SFA occur under test for the cathode of SOFCs. As SOFC cathodes, the area-specific resistances of the SFA-SDC cathodes on the LSGM electrolyte with SDC 10, 20 and 30 wt.% at 800 oC are 0.089, 0.068 and 0.087 Ω cm2, respectively. The peak power density of the SFA-SDC20 on a 300 μm-thick LSGM electrolyte reach 512 mW cm−2 at 800 °C.

ABSTRACTMicro-solid oxide fuel cells (Micro-SOFCs) with yttrium-doped barium zirconate (BZY) and strontium and cobalt-doped lanthanum scandate (LSScCo) electrolytes were fabricated for low-temperature operation at 300 °C. The micro-SOFC with a BZY electrolyte could operate at 300 °C with an open circuit voltage (OCV) of 1.08 V and a maximum power density of 2.8 mW/cm2. The micro-SOFC with a LSScCo electrolyte could operate at 370 °C; its OCV was about 0.8 V, and its maximum power density was 0.6 mW/cm2. Electrochemical impedance spectroscopy revealed that the electrolyte resistance in both the micro-SOFCs was lower than 0.1 Ωcm2, and almost all of the resistance was due to anode and cathode reactions. Although the obtained maximum power density was not sufficient for practical applications, improvement of electrodes will make these micro-SOFCs promising candidates for power sources of mobile electronic devices.
