MEMBRANE ELECTRODE ASSEMBLY AND METHOD FOR MAKING THE SAME

摘要

A method for making membrane electrode assembly includes providing a proton exchange membrane and two electrodes. An array of carbon nanotubes is formed on a substrate. The array of carbon nanotubes is pressed by a pressing device to form a carbon nanotube film. A catalyst layer is formed on the carbon nanotube film to obtain an electrode. Two electrodes are disposed on two opposite surfaces of a proton exchange membrane, to obtain the membrane electrode assembly.
