Patent ID: 7378172

Claim:
A tubular Membrane Electrode Assembly (MEA) with leading wire, comprising a tubular proton membrane, an electrode catalyst and a tubular conductive layer with leading wire, being wrapped and folded in layers, characterized in that: an original mold of a tubular proton-exchange membrane is made of a polymer through a high temperature melting and extrusion; said original mold is transformed into a tubular proton membrane having a proton-exchange function through an ion exchange; an electrode catalyst slurry made by mixing an electrode catalyst and a base material with a proton-exchange membrane is coated on said tubular conductive layer with leading wire and is inserted into said tubular proton membrane; tubular heat-compression molds are deposed outside and inside of said tubular conductive layer; and, after being heated and pressed, said heat-compression tubular mold is knocked out to obtain said tubular MEA with said leading wire.
