VINATech Carbon Control Technologies

The carbon support is a key material for fuel cell catalyst, and the efficiency and durability of the fuel cell are greatly affected by the characteristics of the carbon support.

VINATech has own mass production technology by commercializing carbon support based on carbon control technology.

VINATech is promoting application and commercialization of other advanced technologies in addition to the currently secured carbon surface/shape control technology, activated carbon and carbon composite technology.
Through continuous development, we are developing carbon support that can further improve the efficiency and durability of fuel cells.
