| Summary: | SOFC material has higher efficiency compared to other fuel cell. The research aim was to
create a fuel cell unit. Electrolyte composite Yttria Stabilized Zirconia (YSZ)-
La0,8Sr0,2Ga0,8Mg0,2O3-? (LSGM) was synthesized by solid phase method. Composite YSZLSGM
was sintered at temperature 1400°C for 12 hours. Pellet composite was formed after
the sintering process. Pellet with thickness of 1 mm and 2 cm diameter was made with
hydraulic press of 250 MPA. X-ray diffraction result of LSGM powder showed cubic
structure with a space group Pm-3m, while YSZ powder showed space group P42/nmc.
La0,8Sr0,2MnO3 (LSM) cathode and Sr2Mg0,2Mn0,8MoO6-? (SMMO) anode were synthesized
by sol gel method. Anode and cathode casted on electrolyte’s surface then. Thin layer anode
and cathode were characterized by X-ray diffraction. LSM has orthorombic structure with
space group Pbnm and SMMO has monoclinic structure with space group P21/n.
Characterization of SOFC’s transection was determined by Scanning Electron Microscope
(SEM). Test of cell performance by determining cell potential showed 392 mV of maximum
potential. The cell was burned by elpiji fuel in air exposure. |
