SELF REGULATING GAS GENERATOR AND METHOD

[0001] A self-regulating gas generator that, in response to gas demand supplies and automatically adjusts the amount of gas (e.g. hydrogen or oxygen) catalytically generated in a chemical supply chamber from an appropriate chemical supply such as a chemical solution, gas dissolved in liquid, or mixture. In some embodiments, the gas generator may employ a piston, rotating rod, or other element(s) to expose the chemical supply to the catalyst in controlled amounts. In another embodiment, the self- regulating gas generator uses bang-bang control, with the element(s) exposing a catalyst, contained within the chemical supply chamber, to the chemical supply in ON and OFF states according to a self-adjusting duty cycle, thereby generating and outputting the gas in an orientation- independent manner. The gas generator may be used to provide gas for various gas consuming devices, such as a fuel cell, torch, or oxygen respiratory devices.
