  2. Electro-galvanic oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Electro-galvanic_oxygen_sensor

    Electro-galvanic fuel cell as used in a diving rebreather to measure the partial pressure of oxygen. Two oxygen cells as used by oxygen analysers for diving gas showing commonly used connectors. An electro-galvanic fuel cell is an electrochemical device which consumes a fuel to produce an electrical output by a chemical reaction.

  3. Oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Oxygen_sensor

    The type of oxygen sensor used in most underwater diving applications is the electro-galvanic oxygen sensor, a type of fuel cell, which is sometimes called an oxygen analyser or ppO 2 meter. They are used to measure the oxygen concentration of breathing gas mixes such as nitrox and trimix . [ 9 ]

  4. Automotive battery - Wikipedia

    en.wikipedia.org/wiki/Automotive_battery

    A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.

  5. Oxygen ion battery - Wikipedia

    en.wikipedia.org/wiki/Oxygen_ion_battery

    Oxygen-ion batteries (Oi batteries) are a type of rechargeable battery that works similarly to lithium-ion batteries. The electrodes in oxygen-ion batteries are perovskite-based ceramics instead of typical lithium-ion battery materials (graphite, iron, etc.). The batteries are fire-resistant, and highly durable.

  6. Deoxygenation - Wikipedia

    en.wikipedia.org/wiki/Deoxygenation

    The term also refers to the removal of molecular oxygen (O 2) from gases and solvents, a step in air-free technique and gas purifiers. As applied to organic compounds, deoxygenation is a component of fuels production as well a type of reaction employed in organic synthesis , e.g. of pharmaceuticals .

  7. Silicon–air battery - Wikipedia

    en.wikipedia.org/wiki/Silicon–air_battery

    The specific energy of the silicon-air battery is estimated to be 8470 Wh/kg and the energy density is about 2109.0 Wh/L. The battery voltage is 1 – 1.2 V. [6] By the use of a dedicated electrolyte flow system, discharge times of more than 1000 hours can be achieved for aqueous electrolytes, which allows for 100% usage of the silicon anode. [11]

  8. Lithium–air battery - Wikipedia

    en.wikipedia.org/wiki/Lithium–air_battery

    The lithium–air battery (Li–air) is a metal–air electrochemical cell or battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow. [1] Pairing lithium and ambient oxygen can theoretically lead to electrochemical cells with the highest possible specific energy.

  9. Mass flow sensor - Wikipedia

    en.wikipedia.org/wiki/Mass_flow_sensor

    The intake air temperature sensor is visible outside, the film-grid is inside. A hot wire mass airflow sensor determines the mass of air flowing into the engine's air intake system. The theory of operation of the hot wire mass airflow sensor is similar to that of the hot wire anemometer (which determines air velocity).
