The research into fuel cells have been extremely popular within the last decade due to its clean generation of energy. However, before it can be fully commercialised, teething issues have to be resolved. One of it being the thermal stability of the materials used. In this report, two fabrication methods of thin film cathode of low temperature solid oxide fuel cell will be compared to determine which method provides better thermal stability. The two methods are thin film sputtering and solvothermal synthesis. For solvothermal synthesis, detailed characterisation will be carried out to provide better understanding towards the fabrication of the nanoparticles before the thin film is prepared proper. The end results proved that synthesising temperature played a larger role in affecting the fabricated nanoparticles as opposed to synthesising time.
