Abstract
The invention relates to a method for inertizing an oxygen-containing first gas present in a protective housing (4) surrounding a fuel cell (1), wherein a prescribed amount of a hydrogen-containing second gas is introduced into the protective housing (4) and at least part of the oxygen present in the first gas is reduced by cold combustion.
Claims16
A method for inertizing an oxygen-containing first gas present in a protective housing surrounding a fuel cell, wherein a prescribed amount of a hydrogen-containing second gas is introduced into the protective housing and at least part of the oxygen present in the first gas is reduced by cold combustion, wherein the oxygen content of the first gas or the oxygen content of a gas mixture of the first and second gas present in the protective housing is measured and the prescribed amount of the second gas to be introduced is determined therefrom.
An apparatus for inertizing an oxygen-containing first gas present in a protective housing surrounding a fuel cell, wherein a controllable gas feed device for a hydrogen-containing second gas into the protective housing is provided, so that at least part of the oxygen present in the first gas can be reduced by cold combustion;
- and, a first sensor for measuring the oxygen content of the first gas or the oxygen content of a gas mixture of the first and second gas present in the protective housing is provided, which transmits a first signal to a control unit for controlling the prescribed amount of the second gas to be introduced.
