英文摘要	a bi-guanidinium bridged polysilsesquioxane composite membrane was fabricated for the first time, which showed impressive hydroxide conductivity and decent alkali-stability. its direct borohydride fuel cell yielded a peak power density of 321 mw cm(-2) at ca. 700 ma cm(-2) and 40 degrees c, which is to our knowledge the highest ever achieved with an anion exchange membrane (aem). the cell could discharge at 200 ma cm(-2) for 50 h with voltage maintained at 0.76 v. the strong basicity and resonance of bi-guanidinium cations are the enabling factor for the good membrane properties and fuel cell performance. this work provides a new strategy for non-ammonium aem fabrication, and the synthetic chemistry involved can possibly extend for fabricating versatile aems with similar structure.
