Electromembrane Process – Part 1: Fundamentals and Mathematical Modelling . In electromembrane processes the cation or anion selectivity of polymeric ion exchange membranes can be used for various applications. Industrially important examples are membrane electrolysis and its reversal, the fuel cell or several electrodialytic processes with mono‐ and bipolar membranes. The electrochemical equilibrium which is responsible for membrane selectivity is discussed together with the relevant transport mechanisms within and outside the membrane. The present status and open questions of modelling electromembrane processes are considered and the efficient combination of the different phenomena into an overall model of an electrodialytic process will be addressed. Applications and a comparison of model simulations and experiments will follow as Part 2 of this survey.
