In basic chemistry courses you will learn that diaphragm prevents mixing of solutions between half-cells while maintaining ionic conductivity. What exactly carries charge through diaphragm if it's neither electrons, nor ions from the solution? What is the molecular mechanism behind that?

Ions do travel through the membrane. However, you usually design the system in such a way that traveling ions are those that will not react directly.

So it's some kind of (double) ion exchanger?
