摘要:
The present invention provides a local hydrophilic gas diffusion layer configured to enhance the water removal performance of a fuel cell For this purpose, the present invention provides a gas diffusion layer in which a region under each of a pair of lands, which receives a clamping pressure of the fuel cell stack, is subjected to local hydrophilic treatment by a simple process, thereby enhancing the water removal performance of the fuel cell stack. In particular, the local hydrophilic gas diffusion layer has a first region under each land of the separator which receives the clamping pressure; and a second region under the gas channel of the separator, wherein the first region is subjected to hydrophilic treatment.
