High Proton Conductivity of Water Channels in a Highly Ordered Nanowire

High Proton Conductivity of Water Channels in a Highly Ordered Nanowire

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 measur...

Description
Summary: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.
