Dioxide Materials’ Sustainion ® anion exchange membranes (AEMs) have much lower area specific resistance (ASR) than the competition. Buy them to get higher currents at the same voltage.
Sustainion® Anion Exchange Membranes
|Membrane||ASR in 1 M KOH, 60 °C||pH Range|
|Sustainion® 37-50||0.045 Ω-cm2||2-14|
|Nafion 115||0.52 Ω-cm2||0-13|
|Fumasep FAPQ-375||0.83 Ω-cm2||0-11|
|Neosepta ACN||>50 Ω-cm2||0-8|
