Hydrogen fuel cell catalyst

The serialized electrocatalyst products have passed third-party testing, with the performance indicators of electrocatalyst uniformity, batch stability and consistency meeting the design requirements. Tested under the three-electrode system, the ECSA of the self-made platinum-based catalyst can exceed 110m2/g, and the mass-specific activity can exceed 320A/g. Electrochemically active specific surface area and mass activity of the electrocatalysts are at the international first-class level.
