Method for operating a compressor, and compressor

Abstract

The invention relates to a method for operating a compressor (100), wherein an ionic liquid (a) is used as an operating liquid, and wherein two different materials (c, d) of the compressor (100) are brought in contact with the ionic liquid (b) and form an electrochemical element. In order to partially balance a voltage (U) of the electrochemical element at the compressor (110), a counter voltage (UG) is applied. The invention further relates to such a compressor (100).
