Abstract

 xCsH2PO4·(1-x)Te(OH)6 composites have been synthesized for the different compositions, x = 0.02, 0.04, 0.05,

0.06, 0.08 (labeled composites A-E). The composites were characterized by Scanning Electron Microscopy (SEM), XRay

Diffraction (XRD), Thermogravimetry (TG) and Differential Thermal Analysis (DTA). Telluric acid, Te(OH)6, added

to cesium dihydrogen phosphate (CsH2PO4) significantly effects the structure, particle size and thermal stability of the

composite material. Enhanced thermal stability could lead to use of CsH2PO4 as an electrolyte in low temperature fuel cells.

Keywords: Solid acids, low temperature fuel cells, composite materials, amorphous materials
