Patent number: 7029779Abstract: A fuel cell is disclosed which is formed on a semiconductor wafer by etching channel in the wafer and forming a proton exchange membrane PEM barrier in the etched channel. The barrier divides the channel into two. A hydrogen fuel is admitted into one of the divided channels and an oxidant into the other. The hydrogen reacts with a catalyst formed on an anode electrode at the hydrogen side of the channel to release hydrogen ions (protons) which are absorbed into the PEM. The protons migrate through the PEM and recombine with return hydrogen electrons on a cathode electrode on the oxygen side of the PEM and the oxygen to form water.Type: GrantFiled: November 9, 2004Date of Patent: April 18, 2006Assignee: Integrated Fuel Cell Technologies, Inc.Inventor: Stephen A.

Publication number: 20050158595Abstract: 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. The gas generator may employ a piston, rotating rod, or other element(s) to expose the chemical supply to the catalyst in controlled amounts. The gas generator may be used to provide gas for various gas consuming devices, such as a fuel cell, torch, or oxygen respiratory devices.Type: ApplicationFiled: November 15, 2004Publication date: July 21, 2005Applicant: Integrated Fuel Cell Technologies, Inc.Inventors: Stephen Marsh, Donald Parker, Peter Pintauro
