Abstract
A method for treating hydrogen-containing and oxygen-containing residual gases of fuel cells, wherein the residual gases are fed to a gas circuit, and a residual gas mixture resulting therefrom is circulated in the gas circuit by a device for converting hydrogen and oxygen to water. In order to reduce the amount of hydrogen and oxygen in the residual gas mixture, at least part of the residual gas mixture is discharged from the gas circuit.
