本文报道了一种基于均苯三甲酸和三聚氰胺结晶组装体（TMA MARM，见图）的质子导电材料。由于组装体的有序结构，水饱和的TMA PERM组装体的质子传导率为5.5 S cm（-1），这是迄今为止测得的最高质子传导率。这种极高的导电性和低成本的材料制造使燃料电池设备的应用成为可能。
A proton-conductive material based on a crystalline assembly of trimesic acid and melamine (TMA⋅M, see picture) is reported. Because of the ordered structure of the assembly, the water-saturated proton conductivity for the TMA⋅M assembly is 5.5 S cm(-1) , which is the highest proton conductivity measured to date. This exceptionally high conductivity and low-cost fabrication of the material make applications feasible for fuel-cell devices.
