New solid polymer electrolyte outperforms Nafion; novel polymer folding

Green Car Congress

Researchers, led by a team from the University of Pennsylvania, have used a polymer-folding mechanism to develop a new and versatile kind of solid polymer electrolyte (SPE) that currently offers proton conductivity faster than Nafion by a factor of 2, the benchmark for fuel cell membranes.

Jilin team develops crystalline porous salts with high proton conductivity; application for fuel cell membranes

Green Car Congress

As reported in the journal Angewandte Chemie , the water content in the channels of the porous salts plays an important role in the proton conduction performance of the materials. Presenting high porosity, the crystalline salts contain polar 1-D channels for which it is easy to confine highly polar molecules e.g. water inside the channels.
