NOVELTY - Emergency system (10) comprises a device for sterilization by using waste heat from a fuel cell system (18), a device for extraction of water from the fuel cell system, a device for processing, cleaning, desalinating and/or sterilizing fluids, a device for treating air, a device for influencing temperature of air, pressure of air and/or composition of air and humidity degree of air, a sterilization device for influencing a purity of air, an absorption cooling device, and a device for generating and/or processing a cleaning fluid or a precursor of the cleaning fluid.    USE - Emergency system for providing vital resources, useful as an auxiliary device for accidents, environmental disasters and/or loss of infrastructures and as a part of a disaster protection chamber, a life raft or a drilling rig, and useful for a mine, a mountain expedition for a dive, a polar expedition and/or military action (all claimed), where the environmental disasters are earthquakes, hurricanes, storms, sandstorms, snowstorms, floods, tsunamis, avalanches, mountain accidents, rock fall, volcanic eruptions, famine, interruptions of a drug supply or drinking water supply, water contamination, air contamination, chemical accidents, nuclear accidents, interruption of a communication system and combat operations.    ADVANTAGE - The emergency system can be economically operated and maintained, and is space-saving, energy-efficient and light-weight.
