Fuel Cell
We have established a value chain for the key materials and components of hydrogen fuel cellsbased on patented carbon materials. Using our own technology, we
are the only ones in the world to batch manufacture supporter-catalyst-MEA. Additionally, we are applying this technology to the mass production of deodorizers.

- VINATech is developing and mass-producing MEA,
a key component of fuel cell stacks. -
MEA is a material that has a decisive impact on the stack output efficiency
and consists of an electrolyte membrane and electrodes on both sides (Anode and Cathode). Hydrogen introduced into the oxidation electrode, the Anode, reacts with the catalyst to decompose into protons and electrons, providing a smooth reaction environment for the Anode and Cathode.
VINATech MEA has the following features:
-
High durability and uniformity
-
Low production cost
