Patent ID: 7829344

Claim:
A device for detection of hydrogen in a gas volume, the device comprising: a device for exothermal catalytic recombination of hydrogen in the presence of oxygen into water; the device having a catalyst that is surrounded by a porous material, wherein the porous material is adapted to allow passing of a gas of the gas volume therethrough; a device for determination of a temperature change occurring during the recombination process, wherein the device for exothermal catalytic recombination of hydrogen in the presence of oxygen into water is connected with the device for determination of a temperature change occurring during the recombination process in such a manner that a substantially faultless determination of the temperature change of the catalyst surface of the device for exothermal catalytic recombination of hydrogen in the presence of oxygen into water occurring during the recombination process occurs; a device for comparison of a stored limit value with the temperature change that occurs during the recombination process; and a device for outputting a signal, wherein the device for comparison of a stored limit value with a temperature change occurring during the recombination process is connected with the device for outputting a signal in such a manner that a signal is output when the stored limit value is exceeded.
