Proton conductive composite membrane was prepared by Infiltrating solid acid to porous beta - aluminamembranes and uniaxial pressing of beta alumina and solid acid mixture. NH4+-β"-alumina, which is expected a inorganic solid electrolyte for high temperature PEMFCs, was prepared by ion-exchange reaction. CsHSO4 was salt have been used as protonic conductor. So, the composite membrane composed with NH4+-β"-alumina andCsHSO4 was prepared, then characterized for their crystallite structure and proton conductivity, using X-ray diffraction(XRD), scanning electron microscope (SEM), impedance measurements. |
