  2. Alkaline water electrolysis - Wikipedia

    en.wikipedia.org/wiki/Alkaline_water_electrolysis

    Alkaline water electrolysis is a type of electrolysis that is characterized by having two electrodes operating in a liquid alkaline electrolyte. Commonly, a solution of potassium hydroxide (KOH) or sodium hydroxide (NaOH) at 25-40 wt% is used. [ 6 ]

  3. Proton exchange membrane electrolysis - Wikipedia

    en.wikipedia.org/wiki/Proton_exchange_membrane...

    The PEM electrolyzer was introduced to overcome the issues of partial load, low current density, and low pressure operation currently plaguing the alkaline electrolyzer. [4] [1] It involves a proton-exchange membrane. Electrolysis of water is an important technology for the production of hydrogen to be used as an energy carrier. With fast ...

    HydrogenPro was founded in 2013 by a team with the experienced electrolyser industry at Norsk Hydro [5] and delivered the largest electrolyser plant in Northern Europe. [6] ...

  6. Anion exchange membrane electrolysis - Wikipedia

    en.wikipedia.org/wiki/Anion_exchange_membrane...

    Using an alkaline solution, usually KOH/NaOH increases membrane conductivity and adds a hydroxide ion conductive pathway, which increases the utilisation of catalyst. The current density of an AEM electrolyser without a PGM catalyst operating at 1 A/cm 2 was reported to require 1.8 volts and 1.57 volts in pure water-fed and 1 M KOH-fed ...

  7. High-pressure electrolysis - Wikipedia

    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 ...

  8. Electrolysed water - Wikipedia

    en.wikipedia.org/wiki/Electrolysed_water

    An AA battery in a glass of tap water with salt showing hydrogen produced at the negative terminal. Electrolysed water (also electrolyzed water, EOW, ECA, electrolyzed oxidizing water, electro-activated water, super-oxidized solution or electro-chemically activated water solution) is produced by the electrolysis of ordinary tap water containing dissolved sodium chloride. [1]

  9. Hydrogenics - Wikipedia

    en.wikipedia.org/wiki/Hydrogenics

    A year later, in 2004, the company acquired Stuart Energy, a manufacturer of hydrogen-generation products based on alkaline electrolyte technology. [ 8 ] [ 10 ] In 2007, Hydrogenics narrowed the focus of its fuel cell activities by exiting the fuel cell testing business and working more on forklift power and backup power markets. [ 8 ]
