Patent number: 10309646Abstract: A portable catalytic combustion heater, wherein fuel vapor (11) and air (10) are supplied to a catalyst (6) which promotes the flameless combustion of fuel and releases that. The fuel is supplied as a liquid, passes through a selectively permeable membrane (8) such that fuel vapor exits the membrane and is fed to the catalyst (6). Additional features include porous supports and means of enhancing and diminishing the catalytic rate of combustion and controlling the heat output.Type: GrantFiled: September 19, 2016Date of Patent: June 4, 2019Assignee: GHT GLOBAL HEATING TECHNOLOGIES AGInventors: Robert G. Hockaday, Patrick S. Turner, Zachary R. Bradford, Marc D. DeJohn, Carlos J. Navas, Heathcliff L. Vaz

Patent number: 6953637Abstract: A selective gas permeable membrane allows hydrogen to vent from a battery while preventing other gases from entering the battery. The surface of the filter membrane also catalytically combusts hydrogen and oxygen if both are evolved inside the battery and retains the resulting water for use in the battery. The membrane is made with a porous plastic substrate coated with a thin metal film permeable to hydrogen, and additional coatings. These coatings protect the surfaces, and catalytically combust hydrogen and oxygen.Type: GrantFiled: June 1, 2001Date of Patent: October 11, 2005Assignee: Energy Related Devices, Inc.Inventors: Robert G. Hockaday, Patrick S. Turner, Zachary R. Bradford, Marc D. DeJohn, Carlos J. Navas, F. Wade Uhrich, Heathcliff L. Vaz, L. Luke Vazul

Patent number: 6645651Abstract: A system of two fuel ampoules that can deliver a reactant by diffusion through one of the ampoule walls to the other, such that when said reactant enters the second ampoule, it reacts with another reactant in said second ampoule, making hydrogen gas as a product. Both ampoules are stored in a fuel impermeable container. These ampoules used with small low power fuel cells which need a steady controlled uniform delivery of vaporous fuel such hydrogen and alcohols. This fueling system provides a simple safe fuel interactive system for small hydrogen fuel cells that prevents inadvertent hydrogen production by any single ampoule being exposed to water or typical consumer environments.Type: GrantFiled: June 1, 2001Date of Patent: November 11, 2003Inventors: Robert G. Hockaday, Patrick S. Turner, Zachary R. Bradford, Marc D. DeJohn, Carlos J. Navas, F. Wade Uhrich, Heathcliff L. Vaz, L. Luke Vazul
