ABSTRACT:
The present invention relates to a device and a method for the detection of hydrogen in a gas volume by means of an exothermal catalytic recombination of hydrogen and oxygen present in the gas volume into water. The amount of energy that is released during such an exothermal catalytic recombination is measured in the form of a temperature difference and is compared with a stored limit value. When a corresponding limit value is exceeded an appropriate signal is output.
