The study of X+ (X=H3O, NH4) - ß”-alumina / Nafion composite membrane for higher temperature PEFCs |
초록 |
The composite membrane for higher temperature PEFCs are prepared using protonic ß”-aluminas as fast ion conductor which are thermal stable at higher temperature and evaluated the characterization of electrolyte. The synthesized X+-ß”-alumina powders were incorporated into Nafion® dispersion and successfully fabricated composite membrane by solution casting method. The membranes were obtained with a uniform thickness of about 80 ㎛. The experimental results show that the properties of composite membrane containing H3! O+ -ß”-alumina was slightly higher than that containing NH4+ -ß”-alumina at low and high operating temperature. |
