A hot-gas-generating apparatus for reacting a propellant comprises a combustion chamber, at least one injector that is arranged upstream of the combustion chamber and can be closed, on the combustion chamber side, to the propellant, electrodes being integrated in said injector, and at least one supply line for the propellant. In this context, the propellant is a monopropellant and a substantially water-free ionic solution having low vapor pressure, preferably with a residual water content of less than five percent by mass, which is capable of self-sustaining combustion at a given combustion chamber pressure, and the electrodes have at least two electrodes of opposite polarity which are suitable for electrically igniting the propellant by means of a flow of current through the propellant when this propellant flows between the opposite-polarity electrodes.

Provided are devices for generating a desired gas or mixture of gases by thermally decomposing a gas-generating composition (e.g. a metal hydride or polymer) using the thermal energy generated by reaction of a heat-generating composition (e.g. a thermite mixture), and methods of making and using such devices. The devices include phase-changing separators, i.e. separators that at least partially melt, vaporize, or sublimate as a result of the thermal energy generated by the heat-generating composition.

An object of the present invention is to provide a gas generating agent having an appropriate initial decomposition temperature, generating a large amount of gas, and generating only a small amount of ammonia gas. The object can be accomplished by a gas generating agent containing a guanidine derivative represented by the following formula (1).
