  • Patent number: 8591718
    Abstract: A method and apparatus for producing a carbon monoxide containing product in which cathode and anode sides of an electrically driven oxygen separation device are contacted with carbon dioxide and a reducing agent, respectively. The carbon dioxide is reduced to carbon monoxide through ionization of oxygen and the reducing agent lowers the partial pressure of oxygen at the anode side to partially drive oxygen ion transport within the device through the consumption of the oxygen and to supply heat. The lowering of oxygen partial pressure reduces voltage and therefore, electrical power required to be applied to the device and the heat is supplied to heat the device to an operational temperature and to the reduction of the carbon dioxide occurring at the cathode side. The device can be used as part of an integrated apparatus in which the carbon dioxide is supplied from a waste stream of a process plant.

  • Patent number: 8287716
    Abstract: The desalination system and method places water from the sea under electrolysis to produce hydrogen and oxygen gas. The system has a chamber that is filled with the hydrogen gas displacing other gases. Once the chamber is filled with only hydrogen gas, the oxygen is introduced to form water vapor within the chamber. Liquid water collects on the lower surface of the chamber, and water vapor condenses on the sidewalls. The condensation creates a partial vacuum in the chamber, causing further water to evaporate from the liquid water on the lower end of the chamber. The condensate is desalinated water, which may be collected. Condensation may be assisted through cooling the wall. The hydrogen and oxygen mix in the chamber undergoes a reaction through electrical spark generation from a spark plug to create the water vapor.

  • Patent number: 8114266
    Abstract: Basically, I want to use soft, shredded, rusty metal as a sacrificial anode to CO2 and H2SO4. The metal is then grounded by an earth ground. The sulfuric acid (powder/gas) will increase the conductivity of a Galvanic Cell/Battery (Rust) and conscript oxygen to do so. The galvanic cell itself (Rust) also conscripts oxygen in its attraction to less noble and dissimilar materials (ferrous metal) and will be forced to do work in the galvanic cell. As oxygen is conducted between the difference of two potentials (Battery/Galvanic Cell), sulfuric acid (a bond breaker) will both contribute to un-fusing oxygen from its carbon in the galvanic cell (Rust), and depositing that carbon onto the carbon-iron found in mild steel. Oxygen is released through its' “work” in the sacrificial anode (mild steel) during the rust process and binding the carbon both by acid deposition and electrolysis to the remaining iron and carbon of rust.

    Abstract: A fuel cell or electrolysis cell stack has force distribution members with one planar and one convex shape applied to at least its top and bottom face and in one embodiment further to two of its side faces. A compressed mat and further a rigid fixing collar surrounds the stack and force distribution members, whereby the stack is submitted to a compression force on at least the top and bottom face and potentially also to two side faces. The assembly is substantially gas tight in an axial direction of the primarily oval or circular shape and can be fitted with gas tight end plates to form robust gas inlet and outlet manifolds.

  • Patent number: 8021525
    Abstract: A PEM based water electrolysis stack consists of a number of cells connected in series by using interconnects. Water and electrical power (power supply) are the external inputs to the stack. Water supplied to the oxygen electrodes through flow fields in interconnects is dissociated into oxygen and protons. The protons are transported through the polymer membrane to the hydrogen electrodes, where they combine with electrons to form hydrogen gas. If the electrolysis stack is required to be used exclusively as an oxygen generator, the hydrogen gas generated would have to be disposed off safely. The disposal of hydrogen would lead to a number of system and safety related issues, resulting in the limited application of the device as an oxygen generator. Hydrogen can be combusted to produce heat or better disposed off in a separate fuel cell unit which will supply electricity generated, to the electrolysis stack to reduce power input requirements.

  • Publication number: 20110100836
    Abstract: Basically, I want to use soft, shredded, rusty metal as a sacrificial anode to CO2 and H2SO4. The metal is then grounded by an earth ground. The sulfuric acid (powder/gas) will increase the conductivity of a Galvanic Cell/Battery (Rust) and conscript oxygen to do so. The galvanic cell itself (Rust) also conscripts oxygen in its attraction to less noble and dissimilar materials (ferrous metal) and will be forced to do work in the galvanic cell. As oxygen is conducted between the difference of two potentials (Battery/Galvanic Cell), sulfuric acid (a bond breaker) will both contribute to un-fusing oxygen from its carbon in the galvanic cell (Rust), and depositing that carbon onto the carbon-iron found in mild steel. Oxygen is released through its' “work” in the sacrificial anode (mild steel) during the rust process and binding the carbon both by acid deposition and electrolysis to the remaining iron and carbon of rust.

  • Publication number: 20100147699
    Abstract: A device for the concurrent oxygen generation and control of carbon dioxide for life support system involves two stages, where a first stage removes CO2 from an exhalent side of a ventilation loop and a second stage employs Ceramic Oxygen Generators (COGs) to convert CO2 into carbon and O2. The first stage includes a plurality of chambers and means to switch the ventilation loop through at least one of the chambers, where CO2 removal is carried out before discharge of the CO2 depleted gas to an inhalant side of the ventilation loop, and to exclude the ventilation loop from the remaining chambers of the first stage, where these chambers are placed in communication with the second stage. The second stage has two portions separated by the COGs such that CO2 and the formed carbon remain on an intake portion from the O2 rich atmosphere on the exhaust side, which is plumbed via a metering valve to introduce the O2 rich atmosphere to the inhalant side of the ventilation loop.
