Abstract

A process for removing NO from exhaust in which NO-containing exhaust is guided to a first electrode on which the NO is anodically oxidized to NO.sup.+, the NO.sup.+ is subsequently transported through an NO.sup.+ -conducting solid electrolyte to a second electrode on which the NO is cathodically reduced.
