Patent number: 6093501Abstract: An improved fuel cell system that utilizes hydrogen and air. The hydrogen of the fuel cell is derived from a hydrogen-generating process wherein H.sub.2 O is passed over a bed of iron material. The hydrogen generating process uses a catalyst, or freshly-ground iron material, or both, and generates the hydrogen for the fuel cell in situ at lower-than-normal temperatures when the H.sub.2 O reacts with the iron material. The fuel cell can be used to power a stationary system or a land vehicle, such as an automobile. The bed of iron material can be replenished periodically or continuously.Type: GrantFiled: March 4, 1999Date of Patent: July 25, 2000Assignee: H Power CorporationInventor: John Werth

Patent number: 5925322Abstract: The present invention relates to a combined cycle system of enhanced efficiency. The system comprises a top stage, such as a fuel cell, a partial oxidation reactor or a heat engine, and an oxygen-enriching device, such as a temperature swing adsorption device or a chemical reactor bed device, as its bottom stage. The bottom stage uses waste heat produced by the top stage to enrich the oxygen content of air that is inputted to the bottom stage, thereby producing an oxygen-enriched gas mixture as the bottom stage output. This output mixture constitutes a superior oxidant which is fed back as an input for the top stage, thus enhancing the energy conversion efficiency, cheapness, and compactness of the combined cycle system as compared to that of ordinary fuel cells, partial oxidation reactors and heat engines that use unenriched air as their oxidant input.Type: GrantFiled: July 18, 1997Date of Patent: July 20, 1999Assignee: H Power CorporationInventor: John Werth

Patent number: 5840270Abstract: The catalyzed method of this invention features a method for operating an electrical automotive vehicle. The method of the invention utilizes a hydrogen-air fuel cell to power an electrical automotive vehicle having electrical drive motors. Hydrogen to fuel the fuel cell is supplied onboard by a bed of iron that is made to react with H.sub.2 O in the presence of an alkaline catalyst at temperatures not exceeding approximately 250.degree. C. The preferred alkali hydroxide is the hydroxide of potassium in a range of concentrations between 50 to 60 percent by weight, with the preferred concentration being about 53%. The hydrogen for fueling the fuel cell is generated onboard the automobile, in situ, by using a storage compartment containing iron materials. The hydrogen is generated by passing heated water over freshly ground iron, which then becomes iron oxide. The vehicle's operator obtains a fresh charge of the new iron materials from an iron fuel station for placement in a compartment of the vehicle.Type: GrantFiled: June 7, 1995Date of Patent: November 24, 1998Assignee: H Power CorporationInventor: John Werth

Patent number: 5629102Abstract: The present invention features a system and a method for operating an electrical automotive vehicle. The system has an electrically-powered automotive vehicle with electrical drive motors. The electricity to power the drive motors is supplied onboard by a hydrogen-air fuel cell which operates by a hydrogen-oxygen reaction. The hydrogen for fueling the fuel cell is generated onboard the automobile by using a fuel storage compartment that supplies iron to a reactor bed. The reactor bed is either a fluidized bed or a catalyzed bed. The vehicle's operator obtains a fresh charge of iron for the fuel storage compartment from an iron fuel station. The iron charge is made up of pellets, sponge iron or particles of iron. The system contains a means for grinding the iron particles, or a catalyst, or both, so that their reactivity with respect to water will become enhanced. The vehicle has a tank for containing a supply of water, as well as a means for heating the water to reactive temperatures.Type: GrantFiled: June 7, 1995Date of Patent: May 13, 1997Assignee: H Power CorporationInventor: John Werth
