ß"-alumina / Nafion composite membranes were successfully prepared using the solution casting method for studying the particle size of H3O-ß"-alumina using inorganic filler. In this work, synthesizedß"-alumina powder/slurry were followed into Nafion dispersion. the particle size of powder is a 300～500 ㎚ and slurry is 40～80㎚. The morphology of the composite membrane have been investigated using SEM. The chemical properties of composite membrane were investigated. : proton conductivity, methanol permeability, proton selectivity, water uptake. The performance of MEA measured at different relative humidity using fuel cell test station. |
