Abstract
A sealing structure for a fuel cell and a method for manufacturing the same, in this structure, a first gas separator, a first gas diffusion layer and a first catalyst on the one side, a proton exchange membrane, a second catalyst, a second gas diffusion layer and a second gas separator on the other side, are in turn stacked, wherein an area of the second gas diffusion layer is smaller than an area of the proton exchange membrane. The area of the proton exchange membrane is not larger than an area of the first gas diffusion layer, and the area of the first gas diffusion layer is smaller than an area of the first gas separator, therefore, the shape of the front edges of these elements are step-shaped. The area obverse to the step shape is filled with cured sealing material.
