A gel type proton conducting polymer electrolyte is provided to ensure excellent proton conductivity in various temperature ranges and reduce corrosion largely. A gel type proton conducting polymer electrolyte includes a dendrimer having sulfonated terminal groups. The sulfonated dendrimer has a number average molecular weight of 100-1,000,000 and a weight average molecular weight of 100-1,000,000. A polymer electrolyte fuel cell includes a fuel electrode, an oxygen electrode, and the gel type proton conducting polymer electrolyte which comprises a sulfonated dendrimer having sulfonated terminal groups and is interposed between the two electrodes. |
