An apparatus is provided to generate a gas by mixing chemicals with water. Typically, the production of gas, particularly oxygen, by combining water with powders and other dry chemicals has not been widely employed. There have existed a number of preexisting barriers such as undesirable flow rates and yields. However, by utilizing multiple reaction chambers the flow rates and yields can be more precisely tailored for a variety of situations that may call for particular flow rates and yields. Additionally, the use of the dry chemicals would allow for a long self-life allowing the apparatus to be particularly useful in emergency situations.

The invention claimed is: 1. A system for generating an oxygen-rich gas, comprising: a housing, a puncturing mechanism, a first cartridge sized to fit within a first portion of the housing, the first cartridge comprising: a first rigid water containment chamber having a first gas exhaust opening positioned in a top portion of the water containment chamber, a first flexible chemical storage pouch positioned within the first water containment chamber, a first pressure delivery channel coupled to the first flexible chemical storage pouch and adapted to couple with the puncturing mechanism, a first foam breaker positioned in an upper portion of the first water containment chamber, a first filter positioned above the foam breaker, a second cartridge sized to fit within a second portion of the housing, the second cartridge comprising: a second rigid water containment chamber having a second gas exhaust opening positioned in a top portion of the water containment chamber. a second flexible chemical storage pouch positioned within the second water containment chamber, a second pressure delivery channel coupled to the second flexible chemical storage pouch and adapted to couple with the puncturing mechanism, a second foam breaker positioned in an upper portion of the second water containment chamber, a second filter positioned above the foam breaker and below the second gas exhaust opening, a manifold fluidly coupling the first gas exhaust opening and to the second gas exhaust opening, wherein each of the first and second flexible chemical storage pouches comprise: a flexible oxygen releasing powder storage pouch comprising: a first side sheet, a second side sheet, a bottom seal coupling the first side sheet to the second side sheet, a catalyst storage chamber positioned within the flexible oxygen releasing powder storage pouch and adjacent to the bottom seal, the catalyst storage chamber comprising: a first web sheet positioned between the first side sheet and the second side sheet, a second web sheet positioned between the first side sheet and the second side sheet, and a web seam coupling the first web sheet to the second web sheet, such that in a first position the web seam faces an interior of the flexible oxygen releasing powder storage pouch. 2. The system of claim 1 further comprising: a exhaust pathway fluidly coupled to the manifold, the exhaust pathway comprising a first curved tubular member, a heat sink thermally coupled to the tubular member, and a bubbler chamber fluidly coupled to the exhaust pathway. 3. The system of claim 1, wherein the web seam has an apex which points upwardly towards the interior of the interior of the oxygen releasing powder storage pouch. 4. The system of claim 1, wherein the web seam is formed with a pressure sensitive seal which designed to be breached when a predetermined pressure is applied through the pressure delivery channel. 5. The system of claim 1, wherein the web sheets are formed from non-permeable laminar sheets which do not react with the catalyst or the oxygen releasing powder. 6. The system of claim 1, wherein the side sheets are multi-layer laminate sheets made from polyester, aluminum foil, polyester and polypropylene. 7. The system of claim 1, wherein the first cartridge is coupled to the second cartridge to form one removable cartridge. 8. The system of claim 1, further comprising at least one additional cartridge fluidly coupled to the manifold, wherein the at least one additional cartridge comprises: an additional water containment chamber having an additional gas exhaust opening positioned in a top portion of the additional water containment chamber, an additional flexible chemical storage pouch positioned within the additional water containment chamber, an additional pressure delivery channel coupled to the additional flexible chemical storage pouch and adapted to couple with the puncturing mechanism, an additional foam breaker positioned in the top portion of the additional water containment chamber, and an additional filter positioned above the foam breaker.
