Abstract: A sensor for hydrogen in a fluid medium has a chamber for electrolyte with a window which is selectively permeable to hydrogen to allow hydrogen to pass from the fluid medium under test into the electrolyte in the chamber. A plurality of electrodes in contact with the ionic liquid electrolyte are used to observe hydrogen concentration by voltammetry. The electrolyte is an ionic liquid. Applications where such a sensor may be used include a wellbore tool for measuring the content of hydrogen in a subterranean fluid, monitoring of fiber-optic cables for damage by hydrogen, corrosion monitoring, and small-scale process plant where hydrogen is part of a gas stream.

Abstract: A Li/CFx primary battery having a lithium-based anode and a fluorinated carbon cathode. The fluorinated carbon cathode includes fluorinated carbon nanoparticles. The structure and size distribution of the carbon precursor carbon nanotubes are configured to provide improved battery performance. The fluorinated carbon nanoparticles can be formed by fluorinating carbon nanoparticles using a fluorine-based reactive gas at a temperature in the range from 300 to 600° C., and the fluorinated carbon nanoparticles can further be used to form the cathode of the primary battery. Producing the Li/CFx primary batter can also include heating the fluorinated carbon nanoparticles under an inert atmosphere before the fluorinated carbon nanoparticles are used to form the cathode of the primary battery.

Abstract: A process for determining a content of hydrogen in a fluid medium includes contacting the fluid medium with a sensor. The sensor has a housing enclosing a chamber containing an ionic liquid electrolyte, a window which is permeable to hydrogen and positioned in an opening in the housing, and electrodes in contact with the ionic liquid electrolyte in the chamber. Hydrogen is allowed to pass through the window from the fluid medium into the electrolyte and the sensor is heated. Temperature and pressure of the fluid medium is determined and electrical potential is applied to the electrodes. The method also includes measuring current flow. The sensor can be used to observe hydrogen concentration by voltammetry. The method and sensor may be used for measuring downhole hydrogen content, monitoring fiber-optic cables for damage by hydrogen, corrosion monitoring, and in small-scale process plants where hydrogen is part of a gas stream.
