Benefits of Pressurized Electrolyzers over Atmospheric Electrolyzers
Most pressurized electrolyzers systems available today are found in pressure ranges of between 10 and up to 40 bars, which meet most needs. Although pressurized electrolyzers with output of up to 70 bars are foreseen in the long term, these are not expected any time soon, as these higher pressures are only required for some specific ...
