Features of VINATech's fuel cell catalyst support products

Fuel cells require micro catalyst particles, 3 nm or below, to improve their catalytic performance. Small particles
cannot be created only with catalysts. Catalysts have to be distributed on catalyst support.

VINATech’s fuel cell catalyst supports are CNF or crystalline carbon-black products which are designed to minimize the shortening of catalysts' life cycle due to corrosion

Carbon is seen to corrode easily at 1.2 V or above, as a result of its reaction to oxygen. Corrosion of carbon contained in
catalyst supports results in deterioration of catalysts' performance and shortening of the fuel cells' life cycle.

VINATech's fuel cell catalyst support showed strong corrosion resistance in a carbon corrosion test based on
electrochemical analysis. Corrosion resistance analyses per catalyst supports are as follows.

Features of VINATech's fuel cell catalyst products

VINATech’s fuel cell catalysts are made of platinum, forming 2.5 to 3.0 nm particles that are characterized by broad
reaction areas and excellent corrosion resistance. They are suitable for applications that improve fuel cells' performance and life cycle.

Our fuel cell catalyst products proved highly resistant to corrosion in a holding test satisfying carbon corrosion
conditions. They also demonstrated a low decrement of reaction area.
