Discover the CLHYNN fuel cell

Adaptable

The CLHYNN solution can be adapted for various applications with different wattages. By connecting the batteries to each other, their respective wattages can be combined.

Practical

The CLHYNN source can be dissociated from the battery. Once depleted, the source can be easily replaced without any pressure, as hydrogen is generated in-situ.

Ecological

CLHYNN hydrogen is green, sourced from water. The solution is fully recyclable, with one component usable as fertilizer. Its production requires no critical raw materials (CRM).

Sovereign and economical

The CLHYNN catalyst is Nickel-based, making it cost-effective and easily accessible worldwide, especially in France (New Caledonia).
