Patent ID: 7763374

Claim:
A method for fabricating electrodes, having electrochemical nano-catalysts supported on carbon nanomaterials, for use in membrane fuel cells comprising the steps of: (a) Adding an electrochemical nano-catalyst synthesized on a carbon nanomaterial with an ionomer solution and a solvent together in a container; (b) Obtaining a well-mixed electrocatalyst mixture through a supersonic oscillation and a speedy stirring; (c) Depositing an electrode base substrate on a funnel of a filtering device and pouring said electrocatalyst mixture on said electrode base substrate for filtering out an electrocatalyst layer and thus obtaining a filtrate; (d) Re-filtering said filtrate for several times until obtaining a limpid liquid; (e) Obtaining said coated electrode base substrate to be covered with a plastic film and then to be pressed under a pressure at a room temperature; and (f) Drying said electrode substrate to obtain an electrode for a membrane fuel cell (MFC).
