  2. Hydrogen therapy - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_therapy

    Hydrogen therapy is the use of molecular hydrogen (H 2) for therapeutic purposes. H 2 has therapeutic benefits due to its antioxidant and anti-inflammatory effects, as well as due to its role as an inducer of gene expression , [ 1 ] H 2 is not cytotoxic or explosive below 4% concentration.

    en.wikipedia.org/wiki/High-pressure_electrolysis

    Ultrahigh-pressure electrolysis is high-pressure electrolysis operating at 340–690 bars (5,000–10,000 psi). [8] At ultra-high pressures the water solubility and cross-permeation across the membrane of H 2 and O 2 is affecting hydrogen purity, modified PEMs are used to reduce cross-permeation in combination with catalytic H 2 /O 2 recombiners to maintain H 2 levels in O 2 and O 2 levels in ...

  5. Electrolysis of water - Wikipedia

    en.wikipedia.org/wiki/Electrolysis_of_water

    Electrolysis of water is using electricity to split water into oxygen (O 2) and hydrogen (H 2) gas by electrolysis. Hydrogen gas released in this way can be used as hydrogen fuel, but must be kept apart from the oxygen as the mixture would be extremely explosive.

  6. Hydrogen production - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_production

    High pressure electrolysis is the electrolysis of water by decomposition of water (H 2 O) into oxygen (O 2) and hydrogen gas (H 2) by means of an electric current being passed through the water. The difference with a standard electrolyzer is the compressed hydrogen output around 120–200 bar (1740–2900 psi , 12–20 MPa ). [ 146 ]

    Hydrogen, as atomic H, is the most abundant chemical element in the universe, making up 75% of normal matter by mass and >90% by number of atoms. [101] In astrophysics, neutral hydrogen in the interstellar medium is called H I and ionized hydrogen is called H II. [102] Radiation from stars ionizes H I to H II, creating spheres of ionized H II ...
