Provided are a membrane/electrode assembly for fuel cell which has excellent proton conducting property as well as improved heat resistance and physical properties, and a fuel cell comprising the same. The membrane/electrode assembly comprises anode and cathode electrodes(100,100') which are opposite to each other; and a polyelectrolyte membrane. The polyelectrolyte membrane comprises a polymer of formula 1. In the formula 1, at least one of X1 to X8 are functional radicals represented by formula 2, and n is an integer of 100-10000. In the formula 2, Y1 or Y2 is independently one element selected from the group consisting of halogen elements or hydrogen, n is an integer of 1-10, and n2 is an integer of 1-10. The fuel cell system comprises at least one electric generator, a fuel supply part for supplying a fuel to the electric generators, and an oxidizing agent supply part for supplying the oxidizing agent to the electric generators. The electric generators comprise the polyelectrolyte membrane, the membrane/electrode assembly positioned on both sides of the polyelectrolyte membrane, and a separator positioned on both sides of the membrane/electrode assembly. And the electric generators generate the electricity by electrochemical reaction of fuel and oxidizing agent. |
