A Complete Research about Synthesizing of PtO in the Form of Octahedral; Some Findings about the Anodic Material of Solid State Oxide Fuel Cells

It’s known very well that solid oxide fuel cells (SOFCs) consist entirely of metal oxides, PtO, YSZ, and LSM and have advantages of high efficiency and durability without expensive catalysts. In this research, octahedral-shaped PtO particles were synthesized by microwave thermal treatment at 300 watt power for 15 min in a microwave chamber to be used as an anode material in solid oxide fuel cells. SEM image and particle size distribution revealed near-perfect octahedral PtO microparticle with sizes ranging from 7.0~10.0 m. The anode functional layer (AFL, 60 wt% PtO synthesized: commercial 40 wt% YSZ), electrolyte (commercial Yttria-stabilized zirconia, YSZ), and cathode (commercial La0.8 Sr0.2 MnO3 , LSM) layers were manufactured using the decalcomania method on a porous anode support, sequentially. The sintered electrolyte at 14700 C for 2 h using the decalcomania method was dense and had a thickness of about 10 m. The cathode was sintered at 12700 C for 2 h, and it was porous. Using humidified hydrogen as a fuel, a coin cell with a 15 m thick anode functional layer exhibited maximum power densities of 0.28, 0.38, and 0.65 W/cm2 at 700, 750, and 8000 C, respectively. Otherwise, when a commercial YSZ anode functional layer was used, the maximum power density was 0.65 W/cm2 at 8000 C.
