    摘要： Provided are a proton conductor for a fuel cell, the proton conductor including a phosphoric acid-based material; and a C8-C20 perfluoroalkylsulfonic acid salt which is dissolved in the phosphoric acid-based material and has excellent oxygen solubility characteristics, an electrode including the proton conductor, an electrolyte membrane for a fuel cell including the proton conductor, and a fuel cell including the electrode and the electrolyte membrane. When the C8-C20 perfluoroalkylsulfonic acid salt is used in the preparation of the electrode and electrolyte membrane for a fuel cell, oxygen solubility is increased in a phosphoric acid-based material and oxygen concentration is increased in a phosphoric acid-based material of the electrode. Thus, reactivity of oxygen reduction which is performed in a cathode is increased. Increased concentration of oxygen in the electrode increases oxygen permeability in the cathode, and thus the resistance against reactants' transfer is decreased. As a result, the cell voltages can be increased using the electrode and the electrolyte membrane, and fuel cells having improved efficiency can be prepared.
