Abstract
Abstract Composites proton conducting material based on cesium dihydrogen phosphate (CDP) doped with zirconium oxide (1−x) CsH 2 PO 4 /x ZrO 2 were synthesized with different concentration having in the range such as x = 0.1, 0.2, 0.3 and 0.4 by ball milling method. The prepared solid acid composites were dried at 150 °C for 6 h. Structural and thermal characterization of solid acid composite proton electrolytes were carried out by X-ray diffractometer, Fourier transform infrared spectroscopy, and Raman spectroscopy respectively. Phase transition of the prepared materials was carried out by using differential scanning calorimetry and conductivity was measured by LC Impedance meter in the range 1 Hz to 400 kHz. The ionic conductivity of ZrO 2 doped CsH 2 PO 4 (CDP) was increased up to 1.3 × 10 –2 S cm −1 at the 280 °C under environment atmospheric humidification which showed high stability as compared to pure CsH 2 PO 4 (CDP). This obtaining result would be useful for establishing and design the next generation fuel cell.
