WebAug 24, 2024 · He was the first to propose a bipolar membrane (BPM) , which is a special ion exchange membrane that consists of an AEM and a CEM . Their combined thickness is less than 10 nm [ 11 , 12 ]. Under the reverse bias of a DC electric field, H + and OH − can be generated by dissociating H 2 O [ 13 ]. WebProfiled ion-exchange membranes are promising for improving the parameters of reverse electrodialysis due to the reduction of pumping power and electrical resistance. The smooth commercial heterogeneous cation-exchange MK-40 and anion-exchange MA-41 membranes were chosen as the initial membranes. ... The same behavior for an …
