Founded by JP Corso, entrepreneur from Chalon sur Saône and professor B. Gauthier-Manuel from Besançon’s FEMTO-ST laboratory, our startup, CLHYNN, proposes a totally disruptive technology of green hydrogen fuel cells, without platinum catalyst, nor any pressurized tank

Green hydrogen fuel cells

Without pressure tank because it produces its own hydrogen

More durable materials

Strategic Risk-Free Sourcing

Resources 1000 times cheaper and 10,000 times less rare than platinum

Perspectives of the Hydrogen sector

Massive global investments (9 billion inv. French State)

Peak transport because currently 30% of GHG emissions.

Source – “Hydrogen Council”

The fuel cell market for vehicles

Cost of vehicle ~80k€

Share of the fuel cell system market
worth several billions of euros

Sector’s restraints

Our value proposal


(3 patents as of now)

Our fuel cell generates its own hydrogen

It uses a nickel catalyst instead of platinum.

It uses several possible materials including commercial materials .

Customer benefits


1000 times less expensive catalyst than the platinum one, and without onerous tank to maintain the gas under pressure


30% to 300% more autonomous for the same tank volume, quick replacement of the H2 source
Technological compatibility with current membranes.

Adoption accelerator

Allows not to wait until the creation of infrastructures

Time to market


no risk of supply disruption compared to platinum, which is one of the eight most strategic metals for France (80% South Africa, 10% Russia)

Competitive position

Ease of use: comparable to the most common technology (PEMFC) low temperature use

Versatility: allows to address the same variety of markets while keeping its broad advantages (unlike methanol batteries, which are toxic)

Business model

Market strategy

Product sales: in very targeted, mature, demanding sectors related to other segments of the transport sector (e.g. intralogistics)

High added value / limited volumes Licence sales: throughout the transport sector, wider High added value/ high volumes

Achieved to date
