Hydrogen Modality Glossary
Quick summary
This glossary defines the core hydrogen concepts used across Hydrogen Machines — the delivery modalities, the PEM/SPE production method, the purity vocabulary and the research language — in plain, non-medical terms.
- Nine canonical definitions covering modality, purity and science.
- Each entry states the specification that actually matters.
- Wellness language only — no medical or therapeutic claims.
Glossary entries
Hydrogen inhalation
Hydrogen inhalation is a general wellness modality in which molecular hydrogen gas produced by a PEM/SPE electrolysis cell is breathed through a nasal cannula during a seated session.
Hydrogen bathing
Hydrogen bathing is a general wellness modality in which molecular hydrogen is dissolved into ordinary bathwater by a PEM/SPE generator so exposure is whole-body for the length of the bath.
PEM purity
PEM purity describes how cleanly a solid-polymer electrolysis cell separates its hydrogen stream from oxygen and cell materials, and it is a hardware and manufacturing property rather than a health claim.
PEM electrolysis
PEM electrolysis (also called SPE electrolysis) is the process of splitting pure water into hydrogen and oxygen across a solid polymer membrane, which is the production method behind every Hydrogen Machines system.
Hydrogen therapy
Hydrogen therapy is an informal umbrella phrase for general wellness routines built around molecular hydrogen, covering inhalation, bathing and hydrogen-rich water rather than any regulated device category.
Hydrogen science
Hydrogen science refers to the body of published research examining how molecular hydrogen behaves in biological systems, an exploratory field that describes mechanisms rather than establishing treatments.
Hydrogen-rich water
Hydrogen-rich water is ordinary drinking water into which molecular hydrogen gas has been dissolved, measured by dissolved hydrogen concentration and distinct from alkaline or ionised water.
Hydrogen production
Hydrogen production, in a consumer wellness context, means generating molecular hydrogen on demand by electrolysis inside the device rather than storing or supplying it from a cylinder.
Hydrogen modality
A hydrogen modality is the delivery format through which molecular hydrogen reaches the body — inhalation, bathing or hydrogen-rich water — and it is the first thing to establish before comparing any specifications.
