The mobile room with an additional unit (10), comprises a fuel cell system (12) and a sea water desalinating component of a desalination device (14, 16, 18) for the desalination of water to be desalinated. The fuel cell system provides the desalination device occasionally or indirectly with a first energy that is a nonthermal energy form, and with a second energy, whose energy form is different from the energy form of the first energy, and provides the desalination device occasionally or indirectly with electric, thermal-, mechanic, hydraulic, pneumatic and/or chemical energy. The mobile room with an additional unit (10), comprises a fuel cell system (12) and a sea water desalinating component of a desalination device (14, 16, 18) for the desalination of water to be desalinated. The fuel cell system provides the desalination device occasionally or indirectly with a first energy that is a nonthermal energy form, and with a second energy, whose energy form is different from the energy form of the first energy, and provides the desalination device occasionally or indirectly with electric, thermal-, mechanic, hydraulic, pneumatic and/or chemical energy. The desalination is based on through-pressing of the water to be desalinated through a membrane (22). The desalination is based upon an evaporation of the water to be desalinated. The desalination device comprises two, three or more desalination steps and a filter for cleaning the water to be desalinated and is arranged for conventional-, cooling-, or drinking water extraction. The additional unit serves an air conditioner. The mobile room comprises a load compensation control that serves a power of the fuel cell system to such periods reinforces to lead to the desalination device in which a total thermal or electric power reduction of the energy consumers (20, 50, 74, 76) is lower than the fuel cell system in an optimal operation area. The mobile room comprises a water jet drive, whose water jet pump occasionally serves to press the water containing in the water to be desalinated through the membrane. The mobile room is a land vehicle, air craft, floatable device or a mobile or half mobile housing. An independent claim is included for a method for desalination of sea water by additional unit for air-conditioning and/or power supply. Die Erfindung betrifft einen Mobilraum mit einem Zusatzaggregat (10), das ein Brennstoffzellensystem (12) und eine entsalzende Komponente (22) einer Entsalzungsvorrichtung (14, 16, 18) zur Entsalzung eines zu entsalzenden Wassers umfasst. Das Brennstoffzellensystem (12) ist dazu vorgesehen, die Entsalzungsvorrichtung (14, 16, 18) zumindest mittelbar mit einer ersten Energie zu versorgen, die eine nichtthermische Energieform ist. Die Entsalzungsvorrichtung ist dazu vorgesehen, zumindest mittelbar mit einer zweiten Energie versorgt zu werden, deren Energieform unterschiedlich zu der Energieform der ersten Energie ist. Außerdem betrifft die Erfindung ein Verfahren zur Entsalzung eines zu entsalzenden Wassers mittels eines Zusatzaggregats (10) zur Klimatisierung und/oder Stromversorgung, wobei das Zusatzaggregat (10) ein Brennstoffzellensystem (12) umfasst und die Entsalzung innerhalb des Zusatzaggregats (10) durchgeführt wird. Die Entsalzung erfolgt unter Zuhilfenahme einer ersten nichtthermischen Energie und unter Zuhilfenahme einer von der ersten Energie unterschiedlichen zweiten Energie. Beide Energien werden von dem Brennstoffzellensystem (12) zumindest mittelbar erzeugt.
