摘要： A membrane-electrode assembly in which an opening, a catalyst layer and a diffusing layer are placed within a cathode active region; a method for manufacturing the same; and a fuel cell system using the membrane-electrode assembly. The membrane-electrode assembly comprises: a cathode with a catalyst layer, an opening in the catalyst layer, and a diffusing layer; an anode with a catalyst layer and a diffusing layer; and an electrolyte membrane between the cathode and the anode. A hydrogen ion generated by oxidizing a liquid fuel is transferred to the cathode via the electrolyte membrane, and returns to the anode without reaction in the cathode, so that the hydrogen ion is reduced in the anode by receiving electrons from the anode, thereby generating hydrogen gas on the anode channel. The hydrogen gas is used as a high efficiency fuel, thereby enhancing the output performance of the fuel cell.
