A gas generation system includes a reservoir for a reactant, a compressor configured to pressurize the reactant in the reservoir using an operating medium delivered into the reservoir, a gas generation component fed with the reactant using a reactant feed line, and a metering element disposed in the reactant feed line between the reservoir and the gas generation component. In addition, a method for operating a gas generation system includes controlling the delivery of compressed operating medium so as to maintain a pressure in the reservoir at a level corresponding to a pressure of the reactant downstream of the reservoir and metering the reactant in a feed line between the reservoir and the gas generation component.
