FBM-PK Bipolar Membranes for Salt Splitting - High Stability, Chemically Resistant, 0.2-0.25mm Thickness(20CM*30CM)

FBM Bipolar Exchange membranes with PK reinforcement consists of an anion exchange layer and a cation exchange layer manufactured using a patented multilayer-coating production technology. The polymer backbone for this bipolar membranes is based on hydrocarbon polymer materials. This composite membranes is chemically stable and mechanically reinforced with woven PEEK. In the intermediate layer between Anion Exchange Layer (AEL) and Cation Exchange Layer (CEL), water is dissociated into OH- and H+ ions when exceeding a potential difference of approximately 0.8 V. The CEL must be directed towards the cathode, the AEL must be directed towards the anode, and the mode of operation has to be reverse biased in order to promote the water dissociation reaction. Under the reverse biased mode, the electrons would be transferred from anode side to cathode side. Water molecules would naturally diffuse into the intermediate layer between AEL and CEL and generation of H+ and OH- ions would occur as a result of water splitting reaction. H+ ions will diffuse out from the CEL layer and migrate into the cathode chamber. OH- ions, on the other hand, would diffuse out from the AEL layer and migrate into the anode chamber.
