Abstract
A device in which an environmental air flow is monitored by a monitoring element and in which a natural gas flow is interrupted by a shut-off element on recognition of an insufficient environmental air flow. To allow a continuous operation of the fuel cell battery the monitoring element is short-circuited by a bridging device and that its operability can thus be checked without the environmental air flow having to be interrupted. This allows a permanent operation of the fuel cell battery.
