Gas generation system with pressurized reactant reservoirs
First Claim
1. A gas generation system, comprising:
- 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;
a metering element disposed in the reactant feed line between the reservoir and the gas generation component; and
a pressure accumulator disposed downstream of the compressor, the pressure accumulator providing a pressurization of the reactant in the reservoir using the operating medium when the compressor is switched off.

Abstract
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.
