A novel hydrogen sensor of the solid composite electrolyte Sb 2O 5 H 2O H 3PO 4 workable at low temperature was studied. The electrode was prepared from Pd powder mixed with graphite and Teflon by the mixture pressing and evaporation method.

• 以Sb2 O5 H2 O H3PO4复合氧化物为固态电解质 ,利用混合压膜和蒸发的方法制作传感催化电极和参考电极 ,研制了室温全固态电解质氢气传感器。
