A new type of hydroxide ion conducting membranes has been developed with polyelectrolyte pore-filled within a porous substrate. The filling polymer exhibits ion conductivity, and the porous substrate mechanically prevents excess swelling of the filling polymer, which can otherwise lead to high liquor electrolyte (or fuel) crossover. In addition, the substrate restricts the change in membrane area between the dry and the swollen state. Several benefits of pore-filling electrolyte membranes have been confirmed. Hence, in this research, we report the work done on the preparation methodology of hydroxide ion conducting pore-filling membranes by particularly using all hydrocarbon polymers which are prepared without an amination process. The prepared membranes are characterized by specific thermal and structural analyses, ion exchange capacity and ionic conductivity. |
