Sel bahan bakar padatan oksida merupakan sebuah teknologi sel bahan bakar yang paling menjanjikan karena ramah lingkungan dan efisiensinya tinggi. Pada penelitian ini, sel bahan bakar padatan oksida difabrikasi menggunakan elektroda dan elektrolit yang telah dikembangkan sebelumnya. Pembuatan sel dilakukan dengan sintesis elektrolit LSGM menggunakan metode fasa padat. Hasil analisis difraksi sinar-X serbuk LSGM menunjukkan struktur kubus dalam grup ruang Pm3m. Serbuk LSGM kemudian dibentuk pelet dengan diameter 2 cm menggunakan penekan hidraulik manual dan dibakar hingga suhu 1450oC. Anoda SMMMO dan katoda LSF disintesis dengan metoda sol gel. Gel anoda dan katoda dilapiskan pada permukaan pelet elektrolit dengan cara tape casting dilanjutkan dengan pemanasan bertahap hingga suhu 1350oC. Hasil difraksi sinar-X lapisan tipis SMMMO dan LSF pada pelet elektrolit dianalisis dengan metoda Le Bail menunjukkan bahwa SMMMO berstruktur monoklin dalam grup ruang P21/n dan LSF berstruktur ortorombik dalam grup ruang Pbnm. Foto SEM pada penampang lintang sel memperlihatkan adanya tiga lapisan yaitu anoda, elektrolit, dan katoda. Uji kinerja sel dilakukan dengan mengukur beda potensial sel saat dibakar menggunakan bahan bakar LPG di udara terbuka dan menunjukkan nilai maksimum sebesar 450 mV.

Deskripsi Alternatif :

Solid Oxide Fuel Cells is the most promising fuel cell technology due to their low or zero pollution and high efficiency. On this research, fuel cell was fabricated using solid electrode and electrolyte which had been previously developed. Cell fabrication process started by synthesis of electrolyte LSGM using solid state method. Analysis of X-ray diffraction for LSGM powder showed its structure was cubic and space group Pm3m. LSGM powder was pressed into pelet of 2 cm diameter using a hidraulik press and sintered to temperatur 1450oC. SMMMO as anode and LSF cathode were synthesised sol gel method. Gel was casted on electrolyte surface by tape casting followed by heating and then sintering at temperatur of 1350oC. Analysis of X-ray diffraction for SMMMO and LSF thin layer on pelet electrolyte showed structure of SMMMO was monoclinic with space group P21/n and structure of LSF was orthorhombic with space group Pbnm. Cross section of the cell viewed using SEM showed that there were three layers. Cell performance was tested by burning the cell with LPG fuel in the air and showed a maximum potential value of 450 mV.
