Abstract
A fuel cell MEA with a border packaging structure. A catalyst coated membrane includes an anode catalyst layer, a cathode catalyst layer, and a proton exchange membrane disposed therebetween. An anode border packaging member is connected between the anode catalyst layer and an anode gas diffusion layer. A cathode border packaging member is connected between the cathode catalyst layer and a cathode gas diffusion layer and adheres to the anode border packaging member at outer edges of the catalyst coated membrane. The anode border packaging member and the cathode border packaging member respectively include two adhesive layers and a substrate layer formed therebetween. The anode border packaging member and the cathode border packaging member are respectively connected between the anode catalyst layer and the anode gas diffusion layer and between the cathode catalyst layer and the cathode gas diffusion layer by the adhesive layers.
