A synergistic approach to achieving high conduction and stability of CsHPO/NaHPO/ZrO composites for fuel cells
Solid acid composites of CsH 2 PO 4 /NaH 2 PO 4 /ZrO 2 with different weight ratios of CsH 2 PO 4 (CDP), NaH 2 PO 4 (SDP), and ZrO 2 were synthesized and characterized. The structure and morphology of the composites were investigated by XRD, FESEM, EDX, and FTIR techniques. The thermal stability and...

enhanced the conductivity above the transition temperatures. Additionally, the composites showed excellent stability. The superprotonic transition behavior was identified at temperatures from 220 to 270 °C. The conductivity of the composites was examined in air and under confined conditions and also their decomposition was investigated. Our findings suggest that NaH
