Anionic Mode Fuel Cell

CLHYNN's fuel cell operates in anionic mode, allowing it to use nickel-based catalysts instead of platinum. This represents a reversal of conventional fuel cell operation principles.

Nickel-based catalyst

A catalyst made from nickel, specifically nanoscale nickel oxide and nickel heterostructures formed on carbon nanotubes, developed as a potential alternative to expensive platinum catalysts.

In-Situ Hydrogen Generation Cartridge

A solid, safe, inert cartridge that generates hydrogen directly at the point of use without requiring pressurized storage, external infrastructure, or refueling stations.
