Our Process
From cell
to your box.
HYDROGENYX is a French brand founded by Paul Fournier. We don't manufacture our products ourselves — and we're open about it.
The Flask is designed in Lyon. Manufacturing is entrusted to an industrial partner specializing in SPE/PEM electrolysis, selected after comparing manufacturers.
Our role: specifications, requirements, transparency. Concentration is checked with DPD reagent: a few drops, the water changes color, and the level is read.
After-sales service, warranty and support in France. We give you something to measure, not logos.
