Patent ID: 8241372

Claim:
A method of manufacturing an electrochemical device, the method comprising: forming a first electrode, comprising: providing a graphitized porous conductive fabric layer; conditioning the graphitized porous conductive fabric layer with a first solution containing a cationic surfactant to form a conditioner layer on the graphitized porous conductive fabric layer; taking out the graphitized porous conductive fabric layer with the conditioner layer from the first solution; and immersing the graphitized porous conductive fabric layer with the conditioner layer in a second solution, containing a plurality of negatively-charged polymer-capped noble metal nanoclusters dispersed in the second solution, to form a polymer-protected electrochemical catalyst layer on the graphitized porous conductive fabric layer by adsorbing the polymer-capped noble metal nanoclusters on the conditioner layer; forming a second electrode; placing a separating membrane between the first electrode and the second electrode; and injecting an electrolyte into a space between the first electrode and the second electrode.
