  • Method for preparing an electrode comprising an electrochemical catalyst layer thereon
    Patent number: 7838065
    Abstract: Disclosed is a method for preparing an electrode having an electrochemical catalyst layer, comprising the steps of: providing a substrate having a conductive layer thereon, immersing the substrate in a first solution having a conditioner to form a conditioner layer on the surface of the conductive layer, and immersing the substrate in a second solution having polymer-capped noble metal nanoclusters to form an electrochemical catalyst layer on the conditioner layer of the substrate. This method can reduce the amount of noble metal used in the electrochemical catalyst layer and is suitable for mass production.
    Type: Grant
