The anion conducting polymer electrolytes consisting of the whole hydrocarbon materials were employed without a halomethylation and amination process in this work. The highly quarternary-aminated electrolyte was introduced into porous hydrocarbon substrates and crosslink-polymerized by UV irradiation. Finally, film-like polymer electrolyte membranes were prepared. The prepared pore-filling membranes are able to drastically decrease fuel crossover from anode to cathode because the porous substrate suppresses a swelling factor of highly quarternary-aminated electrolytes in water media such as highly relative humidified operation conditions. The physico-chemical properties of the prepared membranes such as swelling behavior, ion exchange capacity, carbonate crossover, and ionic conductivity were investigated in correlation with the electrolyte composition. |
