A device for recombination of hydrogen and oxygen with the aid of a catalyst system comprises the catalyst system in a housing 1, which has at least one inlet opening and at least one outlet opening, which are sealed by means of first seals 7 which open as a function of temperature. In this housing, a gas-permeable filter system is also provided in such manner that after opening of the first seals, the gases or gas mixtures entering the inlet opening do not reach the catalyst system until they have first passed through the filter system. The filter system is essentially impermeable to aerosols and grease. Housing 1 comprises at least one additional opening, which is sealed gas-tight by means of a second seal 5a, 5b which opens as a function of temperature, with the response temperature of this second seal being higher than that of the first seals, and with the second opening being provided in the housing in such fashion that the catalyst system, after opening of the second seal, is exposed directly to the atmosphere surrounding the housing without interposition of the filter system.
