摘要：
The present specification discloses a polymer electrolyte fuel cell characterized in that each of the cathode and the anode comprises catalyst particles, a hydrogen ion-conductive polymer electrode, a conductive porous base material and a water repellent agent, and water repellency of at least one of the cathode and the anode varies in a direction of thickness or in a plane direction. As such, by varying the degree of the water repellency of the cathode and the anode on the basis of a position, an excellent polymer electrolyte fuel cell having a high discharge characteristic or more specifically a high current-voltage characteristic in a high current density range.
