Purified hiydrogen is obtained by impressing a potential gradient across a cell containintg two efficient electrodes separated by a barrier electrolyte phase and passing an impure hydrogen stream into the anode compartment. Power requirements are low and can be controlled through thle resistance of the electrolyte. The technique can also be used for pumping and accurate metering.
