Abstract

This invention relates to an electrochemical half cell having a gas diffusion electrode as an anode or cathode, in which the gas space behind the gas diffusion electrode is optionally partitioned, for pressure equalization, into gas compartments which are joined to the gas diffusion electrode and which can be removed from the half cell or changed as a unit.
