[0102] Example 5: Manufactured by Shodex Connect 2 AT-80M
[0103] Column temperature 40°C
[0104] Mobile phase solvent DMAc (to make LiBr reach 10mmol / dm 3 way to add)
[0105] Solvent flow 0.5mL / min
[0106] In addition, the proton conductivity was measured by the alternating current method under conditions of a temperature of 80° C. and a relative humidity of 90% using the solvents described in each example by solution casting. The ion exchange capacity (IEC) was obtained by titration.
[0107] Fabrication of Membrane Electrode Assembly
[0108] 603 mg of platinum-supported carbon (manufactured by E-tec) carrying 30 wt % of platinum and 13.2 mL of ethanol were added to 6 mL of Nafion solution (5 wt%, manufactured by Aidrich), and stirred well to prepare a catalyst layer solution. This catalyst layer solution was applied on a gas diffusion layer (carbon cross) by screen printing so that the platinum loading density was 0.6 mg / cm 2 , the solvent was r...
Synthetic example 1
[0114] (Synthesis of Sodium 3-(2,5-dichlorophenoxy)propanesulfonate)
[0115] Under an argon atmosphere, 150ml of DMAc, 75ml of toluene, 24.15g (148.2mmol) of 2,5-dichlorophenol, 47.10g (444.4mmol) of sodium carbonate were charged into the flask, heated and stirred, and the azeotropic mixture of toluene and water After dehydration under low conditions, the toluene was distilled off. After standing to cool at room temperature, 50.00 g (222.2 mmol) of sodium 3-bromopropanesulfonate was added, the temperature was raised to 100° C., and the mixture was stirred at the same temperature for 10 hours. After standing to cool, the solid was removed by suction filtration, a large amount of chloroform was added to the obtained filtrate, and the precipitated white solid was separated by filtration. Furthermore, 35.2 g of sodium 3-(2,5-dichlorophenoxy)propanesulfonate was obtained by the recrystallization method (yield: 77%).

Embodiment 1
[0118] Under an argon atmosphere, 70 ml of DMSO, 2.50 g (8.14 mmol) of sodium 3-(2,5-dichlorophenoxy)propanesulfonate obtained in Synthesis Example 1, 2,5-dichlorodiphenyl 5.11 g (20.35 mmol) of ketone and 13.63 g (87.30 mmol) of 2,2'-bipyridine were stirred, and the temperature was raised to 60°C. Then, 21.83 g (79.36 mmol) of nickel (O) bis(cyclooctadiene) was added thereto, the temperature was raised to 80° C., and the mixture was stirred at the same temperature for 9 hours. After standing to cool, the reaction solution was poured into a large amount of 4N hydrochloric acid to precipitate the polymer, filtered, washed with water until the filtrate became neutral, and then dried under reduced pressure to obtain 5.38 g of polybenzenesulfonic acids, the target product.
[0119] Mn=20000, Mw=300000
[0120] IEC=1.45meq / g (calculate a / (a+b)=0.28)
[0121] Proton conductivity 1.75×10 -2 S / cm (DMSO is used for casting film)
