| 英文摘要 | A novel polymer enriched with quaternary ammonium cation groups and having a star-branched crosslinking network is synthesized from bulky diphenylanthracene, the flexible 1, 6-dibromohexane and tris(dimethylaminomethyl) phenol. The enriched quaternary ammonium cations enable the membranes with both high anion exchange capacity and acid doping levels. The prepared membranes show a proton conductivity of 262 mS cm(-1) and a hydroxide conductivity of 149 mS cm(-1) at 80 degrees C under 100 % relatively humidity. The hydrated membrane with exchangeable hydroxide ions exhibits a tensile stress at break of 44.7 MPa at room temperature. A steady proton conductivity and a hydroxide conductivity retention rate as high as 93 % are achieved by the prepared membranes after soaking in 3 mol/L H2SO4 or 6 mol/L KOH at 80 degrees C for 1000 h. A current density of 996 mA cm(-2) is obtained at 80 degrees C under 2.0 V by the amphoteric water electrolytic cell using the prepared membrane as the diaphragm. The energy consumption of this system is 2.7 kWh Nm(-3) operating at a current density of 100 mA cm(-2) for 64 h, offering a possibility of low energy consumption for hydrogen production. |
