Abstract
An electrode membrane assembly structure comprises a substrate, two active catalytic layers, each active catalytic layer consisting of micro-particle metal layer(s) and porous conducting layer(s) arranged alternately, and a solid polymer membrane layer being sandwiched in said two active catalytic layers and having protonic conductivity. And a method for manufacturing an electrode membrane assembly comprises the steps of forming an active catalytic layer comprising micro-particle metal layers and porous conducting layers on a substrate by plasma sputtering deposition and chemical vapor deposition (CVD), respectively; then forming a solid polymer membrane layer having protonic conductivity on said active catalytic layer by chemical vapor deposition; and followed by further forming another active catalytic layer on said solid polymer membrane layer, all under the condition of vacuum environment, to obtain the electrode membrane assembly.
