Electrolysis and drift currents

Hi,
If there is an electrolysic in a vat, there is a positive and negative drift current betwwen the electrodes.
Is it possible to have a situation where there is only one (either positive or negative) drift current?
Thanks

I don't think so, because in electrolysis you're ripping electrons off of their atoms. This results in a separation of charges and if you don't pull the positive ions away you'll quickly run into a situation where the positive charge buildup is so large that you can no longer pull any electrons away, stopping the electrolysis process.

But in a conductor, if we apply a potential suddenly, the light electrons can move easily but the heavier positive ions cannot.
