NOVELTY - The method comprises forming a first electrode, 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. The first electrode is formed by immersing a graphitized porous conductive fabric layer (420) in a second solution containing polymer-capped noble metal nanoclusters dispersed in the second solution to form a polymer-protected electrochemical catalyst layer on the fabric layer, and conditioning the fabric layer with a first solution.    USE - The method is useful for manufacturing an electrochemical device such as fuel cells or solar cells.    ADVANTAGE - The method is capable of effectively and economically manufacturing the electrochemical device with improved catalytic performance, stability, desired quality and less power consumption.    DETAILED DESCRIPTION - The method comprises forming a first electrode, 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. The first electrode is formed by immersing a graphitized porous conductive fabric layer (420) in a second solution containing polymer-capped noble metal nanoclusters dispersed in the second solution to form a polymer-protected electrochemical catalyst layer on the fabric layer, conditioning the fabric layer with a first solution containing a surfactant to form a conditioner layer on the fabric layer, attaching the fabric layer with the polymer-protected electrochemical catalyst layer to a substrate, and forming the graphitized porous conductive fabric layer on a substrate. The graphitized porous conductive fabric layer comprises a fabric made from carbon fibers or a carbon containing layer graphitized at a high temperature for forming the first electrode, and is polymerized by polymer. The polymerized graphitized porous conductive fabric layer is cured to form a support portion for forming the first electrode. The second electrode is formed by forming a dye-impregnated oxide layer (430) on a second substrate, and forming a porous conductive layer between the second substrate and the dye-impregnated oxide layer. An INDEPENDENT CLAIM is included for a method for forming an electrode including an electrochemical catalyst layer.
