Fuel cell catalyst technology

The fuel cell catalyst is the main material of MEA electrodes, and the fuel cell catalyst production technology is one of the original technologies of fuel cell.
"VINATech develops and produces various types of alloy catalysts and low platinum loading catalyst according to market demands."
VIANTech has technology for controlling metal catalyst particle size and Pt loading.

VINATech's fuel cell catalyst

  • - High activity and high Electrochemical Surface Area(ECSA)
  • - High durability and good metal stability(made with VINATech's carbon support)
