The present invention includes a device for hypoxia training including a breathable gas source; a mask in fluid communication with the breathable gas source; a mask-state detector that uses one or more criteria to determine if the mask is being worn by a subject, wherein the mask-state detector is capable of communicating an indication of a mask-off state or a mask-on state; a flowmeter in fluid communication with the mask and coupled to the mask-state detector; and a pressure regulator in fluid communication with the mask and with the breathable gas source, and coupled to the mask-state detector, wherein the pressure regulator sets a first pressure at the mask when the mask-state detector communicates an indication of a mask-off state or a second pressure at the mask when the mask-state detector communicates an indication of a mask-on state.

Hypoxia training device

The present invention includes a device for hypoxia training comprising: one or more electrochemical cells each comprising: a cathode and an anode separated by a proton exchange membrane, each of the anode and cathode in communication with an input and an output, wherein the input of the cathode is in fluid communication with ambient air, and wherein the input of the anode is in fluid communication with a source of liquid water; a power supply connected to the one or more electrochemical cells; and a mask in fluid communication with the output from the cathode of the one or more electrochemical cells, wherein oxygen is removed from the ambient air during contact with the cathode when hydrogen ions separated from liquid water by a catalyst on the anode convert oxygen in the ambient air into water.

The present invention includes a method including providing an anode and a cathode; providing a desalination device operably coupled to establish an electrical potential between the anode and the cathode when the desalination device is operating; providing water containing dissolved solids; thereby establishing the electrical potential; reducing a salinity of the water by supplying the water to the desalination device; and generating electrical power by reducing the salinity of the water.

Integrated energy generation and desalination system and method

An apparatus and method apply water to a hydrogen-containing composition, such as a hydride, in the presence of a catalyst that promotes hydrolysis to generate hydrogen in a controlled manner. The amount of catalyst used can be carefully tailored so that the reaction rate is limited by the amount of catalyst present (passive control) or it can be sufficiently large so that the reaction is controlled by the rate of water addition (active control).

Hydrogen generator

Protecting a membrane and electrode assembly in an electrochemical cell having one or more electrocatalysts in intimate contact with the membrane during storage or shipment of the cell. The membrane may be provided in either the non-proton form of a dry or hydrated cation exchange membrane, such as an alkali metal cation form or an ammonium cation form; the wet or dry precursor form of a cation exchange membrane, such as the non-ionically conducting sulfonyl-fluoride polymer membrane; or the dry proton form of a cation exchange membrane. These membrane surfaces are not acidic under open circuit conditions experienced during storage or shipment of the cell. Since some electrocatalysts are degraded during contact with the acidic surface of a hydrated membrane, the non-acidic surface of the membrane protects these electrocatalysts. The method may be used on newly assembled electrochemical cells, on cells being taken out of service, and on membrane and electrode assemblies.

Preparation and storage of membrane and electrode assemblies

A bipolar assembly for use in electrochemical cell stacks, especially stacks operated at low pressure. The bipolar assembly is lightweight and provides a 'post-type' flow field that operates with a low pressure drop. The bipolar assembly comprises a gas barrier having an array of electronically conducting posts disposed approximately perpendicular to the gas barrier. Each end of the posts is in electrical communication with the surface of an electrode. Because the bipolar assembly separates a cathode from an anode, the posts contact an anode electrode on one end and a cathode electrode on the other end. The posts provide current conduction through the stack as well as provide the flow fields for the electrochemical reactants. Optionally, the bipolar assembly may contain cooling fluid channels formed by adding additional gas barriers to the bipolar assembly. The space between the gas barriers form a channel through which cooling fluids may be circulated.

Electrochemical cell and bipolar assembly for an electrochemical cell

A subassembly for a stack of electrochemical cells that includes a porous metal sheet having a first face and a second face with a hydrophobic, carbonaceous gas diffusion layer disposed within the pores along the first face of the porous metal sheet. The second face of the porous metal sheet defines a flow field while that portion of the porous metal sheet filled with the gas diffusion layer forms a current collector. The subassembly may further include a metal gas barrier metallurgically bonded to the second face of the porous metal sheet to act as a gas barrier between the porous metal sheet and a second porous metal sheet having a second gas diffusion layer disposed within the pores along a face of the second porous metal sheet. Preferably, the gas diffusion layers are applied as a paste to the porous metal sheet and then dried.

Unitized barrier and flow control device for electrochemical reactors

An apparatus for electrochemical impedance spectroscopy having a solid electrolyte is disclosed. The apparatus has a chamber made of an electronically insulating material, a solid electrolyte coupled to the chamber and an electrode disposed in the chamber. A biasing member is used to urge the electrode towards the solid electrolyte and urge the solid electrolyte toward the substrate. The solid electrolyte is designed to contact the surface to be tested directly with no corrosive or otherwise harmful effect to the surface. A method for the detection of corrosion in bare or coated metallic substrates is also provided.

Electrochemical impedance evaluation and inspection sensor

The present invention provides a self-replenishing liquid water source onboard an automobile for supplying liquid water to an electrolyzer, such as an on-board hydrogen generator useful for the suppression of unwanted emissions. While automobiles typically have water reservoirs resupplied by a person, the invention provides a passive means of water collection for reliable replenishment due to operations of the automobile itself. The invention provides condensate from the engine exhaust gas by cooling a region of the exhaust system using cooling fluid from the engine coolant system. The cooling fluid is circulated during a period following the engine cold start event when the heat load on the engine coolant system is low.

Water sources for automotive devices

The invention provides for reducing the number of parts and the number of interfaces found in certain types of chemical reactors, particularly in electrochemical reactors, and especially in the type or reactor known as a fuel cell or fuel cell stack This reduction comes from the use of a unified structure that combines the functions normally carried out by several components in the unit, particularly by combining the functions of the gas distribution structure and the gas diffusion structure, the gas distribution structure and the gas barrier structure, or all three structures into a single, unitary, metallic part. This offers the advantages of simplified design, better performance, and lighter weight.

Water sources for automotive electrolyzers

Thin, light weight bipolar plates for use in electrochemical cells are rapidly, and inexpensively manufactured in mass production by die casting, stamping or other well known methods for fabricating magnesium or aluminum parts. The use of a light metal, such as magnesium or aluminum minimizes weight and simultaneously improves both electrical and thermal conductivity compared to conventional carbon parts. For service in electrochemical cells these components must be protected from corrosion. This is accomplished by plating the surface of the light weight metal parts with a layer of denser, but more noble metal. The protective metal layer is deposited in one of several ways. One of these is deposition from an aqueous solution by either electroless means, electrolytic means, or a combination of the two. Another is deposition by electrolytic means from a non-aqueous solution, such as a molten salt.
