| Summary: | Cathode-carbonate is prospective materials for low temperature solid oxide fuel cells (LTSOFCs). The influence of carbonate on the properties of cathode LT-SOFCs is studied. Difference amount of binary carbonate (Li2C03:Na2C03i)s prepared at molar ratio of 67:33 and 62:38.The cathode composite powders were calcined at 750°C for 2 hours before uniaxial press. XRD results confirmed
that carbonate in cathode composite exist as amorphous phase when no additional peaks was observed in the XRD pattern. Thik exhibits carbonate has a good compatibility with
cathodes composite powders. The developed cathode composite also gave the acceptable porosity values between 25 to 27%. The finding shows that the amount of binary carbonate in cathode composite has some influences on its properties. |
