Abstract:Micro-solid oxide fuel cells (SOFC) sensors prepared via depositing a thin film BYCF (10 wt% [Ba0.95FeY0.05O2.8] + 90 wt% [Co2O3]) – GDC20 (Gd0.20Ce0.80O1.95) cathode and NiO-GDC20 (Gd0.20Ce0.80O1.95) anode on a GDC20 electrolyte layer were operated at 800 °C. The structure, which receives only biogas, was formed into 15-mm pellets with only one side for detecting methane (CH4). The detection of 40% to 99.99% CH4 provided a high level of accuracy compared with 10% to 30% CH4. The biogas (60% CH4) from the Oil … Show more
