Patent ID: 7883654

Claim:
A method for fabricating a membrane electrode assembly (MEA), comprising steps of: (a) obtaining a MEA chamber having a vacuum facility, said vacuum facility having a suction plate, a proton exchange membrane (PEM) being fixed on said suction plate through a vacuum effect, a template being deposed on said PEM, said template having a hollow; (b) inputting a slurry of catalyst material into said hollow of said template, a binding being processed at a binding processing temperature selected from a group consisting of a room temperature and a binding temperature of said slurry of catalyst material and said PEM, said binding processing temperature at which the binding is processed being obtained by activating a temperature-controllable heater to heat up a temperature of said suction plate; (c) keeping said suction plate at said binding processing temperature and pressing a pressing plate having a convex part into said hollow of said template at said catalysis temperature to obtain a first catalyst electrode layer (CEL) on a surface of said PEM; (d) after obtaining said first CEL on said surface of said PEM, cooling down said template, taking said template out of said vacuum facility, turning over said PEM, re-activating said vacuum facility to fix said PEM on said suction plate through said vacuum effect, and then deposing said template on another surface of said PEM; (e) inputting said slurry of catalyst material into said hollow of said template again, a binding being processed at said binding processing temperature; and (f) keeping said suction plate at said binding processing temperature and pressing said pressing plate having said convex part into said hollow of said template again at said binding temperature to obtain a second CEL (CEL′) on said another surface of said PEM and to obtain a MEA having three layers (MEA-3-layer) of CEL+PEM+CEL′.
