The present invention relates to a polymer electrolyte fuel cell bipolar plate and a polymer electrolyte fuel cell using the same having a pattern for the movement of water within the channel. A polymer electrolyte fuel cell of the present invention, a film having a film positive electrode and the polymer electrolyte membrane arranged between the cathode-electrode assembly, membrane-electrode first and second gas diffusion layers disposed on both sides of the assembly and the first and the 2 are disposed on both sides of the gas diffusion layer and has a first and a second separating plate that is the channel is formed, and a plurality of unit cells that are stacked; The two end plates that are disposed on both sides of the plurality of unit cells and; And it concluded that the end plate comprises a fastening means. The first and the hydrophobic / hydrophilic pattern to the movement of the water in the channel of the bipolar plate adjacent to the cathode of the second separating plate is formed. According to the present invention, since it is formed with a hydrophobic / hydrophilic pattern within the channel of the separation plate facilitate the movement of water, the water overflow is prevented can be prevented from lowering and life shortening of the performance, to improve the properties of the cold-start there are excellent effects.
