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.

An array of power cells having three-dimensional geometric structures encompassing respective volumes include membranes with catalyst on each side. Cover(s) coupled to the membranes separate first flow paths from at least one second flow path at the membranes. Fuel and oxidant flow to the array of power cells in a parallel manner, and react with the catalyst to produce power. A control circuit may be extended to an array of power cells or array of banks of power cells to configure the cells or banks in series-row and column combinations to generate power in a selectable manner. The array can be produced on silicon wafers using high volume manufacturing techniques, and intelligence can be placed in chips, disks, or stacks with the array. The power cells can also act as electro-chemical reactors.
