摘要： A multi-gas microsensor assembly for simultaneously detecting carbon dioxide and oxygen in real time. According to one embodiment, the assembly comprises a non-conductive, solid substrate. A plurality of sensing electrodes, a single reference electrode, and a single counter electrode are positioned on one side of the non-conductive, solid substrate. In addition, all of the electrodes are in intimate contact with the same side of a solid-polymer electrolyte anion-exchange membrane, the solid polymer electrolyte membrane having at least one gas diffusion opening aligned with each sensing electrode. The sensor is operated in a three-electrode potentiostatic mode, in which a constant potential is maintained between the sensing and reference electrodes, and the current is measured between the sensing and counter electrodes. Control of the electrodes is achieved with a small bi-potentiostat. The design of the bi-potentiostat allows at least two different sensing electrodes to share the same counter and reference electrodes.

摘要： Disclosed are methods and systems for generating hydrogen gas at pressures high enough to fill a hydrogen storage cylinder for stationary and transportation applications. The hydrogen output of an electrochemical hydrogen gas generating device is integrated with an electrochemical hydrogen compressor operating in a high-differential-pressure mode. The compressor brings the hydrogen produced by the gas generating device to the high pressure required to fill the storage cylinder.

摘要： Disclosed is a novel proton-exchange membrane (PEM) based solid polymer electrolyte electrochemical oxygen control (EOC) system that can deplete and control the oxygen from a closed container to levels sufficient for both disinfestation and preservation. With the use of this electrochemical process, many insects that infest raw agricultural products and other produce can be exterminated, without detriment to the quality of the produce and without deposition of harmful residue, by reducing the ambient oxygen to a controlled low level for several days. The electrochemical process features the use of a bipolar stack comprised of a selected number of PEM cells connected electrically in series and separated by an electrically conductive bipolar plate. Each cell contains a membrane and electrode assembly, consisting of an anode structure and cathode structure in intimate contact with a PEM. When DC power is applied to the cell stack, electrons are supplied to the cathode, supporting reduction of oxygen at the cathode with the formation of water, and electrons removed from the anode, supporting oxygen evolution by the decomposition of water at the anode. The anode and cathode compartments are separated by the solid ionomer PEM, which transports protons generated at the anode through the PEM to the cathode to complete the electrical circuit internally. Oxygen is depleted by recirculating the gas in the dosed container over the cathode, and expelling the oxygen evolved at the anode by separating the oxygen from the recirculating anode water stream and venting it to the outside of the closed container. Nitrogen or other inert gas is added as makeup gas to avoid creating a negative pressure in the container. A unique feature of this process is that at a low oxygen concentration, the cell and stack cathode current becomes rate-limited in direct proportion to the oxygen level in the recirculating gas and can therefore be used as a measure of the container oxygen level. In the sensing/control scheme developed as part of this invention, the current is periodically allowed to rise to the diffusion limit in a “measure mode” and then reset according to the desired oxygen level, determined from a slope-intercept “measure mode” calibration curve, for a longer “control mode” period.

摘要： This invention relates to the discovery that during operation and/or shutdown of electrochemical and gas generating devices corrosive materials are released from hardware and components employed therein and that such materials are principally responsible for observed pitting and perforation failure of the metallic hardware, including the separator/collector sheets, of these devices that serve to partition and hermetically seal compartments that support a hydrogen atmosphere. This invention therefore particularly relates to a method for improving the reliability of such devices by reducing brittle failure and perforation failure of these separator sheets by providing a composite separator sheet made up of a layer of a material resistant to molecular hydrogen embrittlement adhered to a layer of a corrosion resistant material. This invention further particularly relates to an improved electrochemical or gas generating device that employs the above-described composite separator sheet such that the hydrogen embrittlement resistant layer of the composite sheet faces the compartment that supports the hydrogen atmosphere.

摘要： The integrated electrochemical/chemical oxygen generating system of the invention includes a water electrolyzer combined with a chemical oxygen generating subsystem which converts hydrogen from the electrolyzer to a decomposable oxygen source such as hydrogen peroxide. The total oxygen output of such a system is greater than that possible from the electrolyzer alone while safely disposing of the electrochemically generated hydrogen.

摘要： Electrolysis cell comprises, in one embodiment, a proton exchange membrane (PEM), an anode positioned along one face of the PEM, and a cathode positioned along the other face of the PEM. An electrically-conductive, compressible, spring-like, porous pad for defining a fluid cavity is placed in contact with the outer face of the cathode. The porous pad comprises a mat of carbon fibers bound together with one or more, preferably thermoplastic, resins, the mat having a density of about 0.2-1.5 g/cm3. Cell frames are placed in peripheral contact with the metal screen and the compression pad for peripherally containing fluids present therewithin. Electrically-conductive separators are placed in contact with the metal screen and the compression pad for axially containing fluids present therewithin. A plurality of the cells may be arranged in series in a bipolar configuration without requiring a separate compression pad between cells (for gas pressure differentials up to about 400 psi or greater). The invention is also directed to a fuel cell wherein the pad replaces the carbon fiber paper or carbon fiber cloth in contact with the cathode or anode.

摘要： A high-voltage electrochemical-electrolytic capacitor. The capacitor includes a cathode comprising a plurality of electrically-conductive particles in intimate electrical contact with one another and disposed in a proton-conductive, electrically-non-conductive, solid ionomer matrix. The capacitor also includes an anode comprising a plurality of electrically-conductive particles in intimate electrical contact with one another and disposed in a proton-conductive, electrically-non-conductive solid ionomer matrix, the electrically-conductive particles of the anode differing in composition from the electrically-conductive particles of said cathode. The capacitor further includes a proton-conducting dielectric positioned between and in contact with each of the cathode and the anode, the proton-conducting dielectric comprising a solid ionomer. Preferably, the capacitor is assembled by constructing a first portion and a second portion, the first portion comprising the cathode and an extra thickness of solid ionomer on its inner surface, the second portion comprising the anode and an extra thickness of solid ionomer on its inner surface. When the first and second portions are brought together, the extended thicknesses of the solid ionomer jointly form the proton-conducting dielectric.
