Why HYDROGENYX
The obsession with measurement.
Paul Fournier is 20 years old. He discovered molecular hydrogen through sports recovery — then delved into the literature: hundreds of studies published since 2007.
Comparing the devices on the market reveals a consistent pattern: concentrations are announced everywhere, but measurements are published nowhere. The European market is rife with unverified claims.
His answer: transparency. An industrial partner specializing in SPE/PEM, selected after comparing manufacturers — and a verifiable concentration with the DPD reagent.
Parcours
From observation
to measurement.
-
The finding
H₂ flasks sold on quantified promises, without published measurements to back them up.
-
Comparison
Study of manufacturers specializing in SPE/PEM electrolysis. Specification grids, samples, tests.
-
The Specifications
A non-negotiable requirement: a verifiable concentration of DPD reagent (reference colorimetric method).
-
The Partner
Selection of a specialized industrial partner. 4th generation SPE/PEM Platinum-Iridium electrolysis cell, BPA-free body.
-
HYDROGENYX Flask
Launch: verifiable concentration with DPD reagent, kit available online (~€20). After-sales service and warranty in France.
My beliefs
Transparency,
line by line.
What you'll never read here
Health promises — molecular hydrogen has been a research field studied since 2007, not a cure.
Inflated review counts or decorative certification badges.
No false urgency — no countdowns, no fake scarcity.
What you can check
The concentration, at your home, of the DPD reagent — kit available online (~€20).
5-year cell warranty: free replacement if the water is no longer correctly enriched (DPD control).
60-day satisfaction guarantee or your money back, customer service in France, response within 24 hours.
In a nutshell
"We're not asking you to take our word for it: you can measure the concentration yourself with the DPD reagent."
