Abstract

Telahdilakukanpembuatanelektrolitpadatuntuk Solid Oxide Fuel Cell (SOFC).Elektrolitpadat SOFC dibuatdaribahanCalsia Stabilized Zirconia (CSZ) dan Magnesium Oxide.Kandungan Magnesium Oxide dalam % berat yang bervariasiyaitu 0%, 0.1%, dan 0,3%. Setelahpencampuran, dilakukanpengepresandiikutidenganpensinteranpadasuhu 14500C selama 4 jam.Impedansikeramikhasil sinter diukurdenganmenggunakanLCRmeteruntukmengetahuikonduktivitasionik. Strukturkristaldianalisisdenganmenggunakan X-Ray Diffractometer (XRD) danstrukturmikrodianalisisdenganmenggunakan Scanning Electron Microscope (SEM). Hasilpengujian XRD menunjukkanbahwaelektrolit CSZ-MgOtidakmengubahstrukturkristal CSZ. Hasil SEM menunjukkanbahwasemakinbesarkomposisiMgO, ukuranbutirsemakinbesar..Secarakeseluruhandapatmeningkatkankonduktivitasionikelektrolitpadat CSZ dari 0,017 mS/cm sampai 0,089 mS/cm.
Febrication of solid electrolytes for an Solid Oxide Fuel Cell (SOFC) has been done. The solid electrolyte for the SOFC made of Calcia Stabilized Zirconia (CSZ) and Magnesium Oxide. The concentration of magnesium oxide in weight% at various of 0%, 0,1%, and 0,3%. After mixing CSZ and magnesium oxide, pressing was done followes by sintering at temperature of 14500C for four hour. Impedance of sintered ceramics was measured using an LCR meter in order to know the ionic conductivity of the ceramics. Crystal structure was analyzed using an X-Ray Diffractometer (XRD) and the microstructure was analyzed using a Scanning Electron Microscope (SEM). The XRD analyses result showed that the CSZ-Magnesium oxide electrolyte notchange thecrystalstructure CSZ. The SEM analyses result showed that the higher the concentration magnesium oxide , the larger grain size. Overall can improve ionic conductivity solid electrolyte CSZ of 0.017 mS/cm until 0.089 mS/cm.
