The role of the salt electrolyt on the electrical conductive properties of a polymeric bipolar membrane [PDF]

open access: yes, 2001
We have studied the contribution of the salt electrolyte to the electrical conductive characteristics of a bipolar membrane. We present first a critical analysis of previous theoretical approaches, and discuss the limits of validity. Experimental current-

Novel membrane concept of internal pH control in electrodialysis of amino acids using a segmented bipolar membrane (sBPM) [PDF]

open access: yes, 2013
In electrodialysis of amino acids, pH-changes play an important role in terms of the efficiency of the process. Due to the zwitterionic character of amino acids, small pH changes may result in significant changes in the charge of the amino acids.

Stable overall water splitting in an asymmetric acid/alkaline electrolyzer comprising a bipolar membrane sandwiched by bifunctional cobalt‐nickel phosphide nanowire electrodes

open access: yesCarbon Energy, 2020
Water splitting has been proposed to be a promising approach to producing clean hydrogen fuel. The two half‐reactions of water splitting, that is, the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), take place kinetically fast in ...

Assymetric bipolar membranes in acid-base electrodialysis [PDF]

open access: yes, 2002
In this experimental study, the influence of asymmetric bipolar membranes on the salt impurities in the acid and base product is investigated. The thickness of one, the other, or both ion-permeable layers of a bipolar membrane is increased.
