Abstract
As an important component in alkaline membrane fuel cells, anion exchange membrane (AEM) often suffers from the tradeoff between ionic conductivity and chemical/dimensional stability. We herein report a partially fluorinated poly(arylene piperidinium) AEM with multication cross-links, which was synthesized by copolymerizing 1,1,1-trifluoroacetone, N-methyl-4-piperidone, biphenyl, and subsequent cross-linking with N1, N6-bis(6-bromohexyl)-N1, N1, N6, N6-tetramethylhexane-1,6-diammonium bromide. The resultant AEM exhibited an excellent OH− conductivity of 148.7 mS cm−1 at 80 °C (IEC = 2.9 mmol g−1) due to the multication structure, which may promote microphase separation to produce wide ion-conducting channels. Compared with those without partial fluorination, the fluorinated AEM showed lower swelling ratio (33% vs. 58% at 80 °C). The ionic conductivity of the AEM remained by 85% after it was treated 1700 h in 1 M NaOH at 80 °C. In addition, the H2/O2 fuel cell assembled with the AEM yielded a peak power density of 208 mW cm−2 at 60 °C. Our work successfully demonstrates the synergistic effect of partially fluorinated backbone and multication cross-linked structure to inhibit membrane swelling while keeping high conductivity; it is beneficial for better balancing AEM conductivity and robustness.
