Abstract: Disclosed are an electrode including a porous substrate, a membrane-electrode assembly for a fuel cell including the same and a method of manufacturing the same. In the method of manufacturing the membrane-electrode assembly, the amount of a catalyst that is loaded depending on the position is applied in a gradational manner, thus efficiently using the catalyst, thereby reducing costs owing to the use of a decreased amount of the metal catalyst. Further, the membrane-electrode assembly includes the electrode including a porous substrate, thus making it easy to select hot-pressing conditions and increasing processing efficiency. The porous substrate is hydrophobic and the pore size in the electrode is not decreased compared to conventional electrodes, thus reducing flooding and generating various operation regions. The electrode including the porous substrate can minimize electrode loss, thus improving electrode durability.
