New solid polymer electrolyte outperforms Nafion; novel polymer folding
Green Car Congress
JUNE 4, 2018
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. Most of these new polymers have amorphous, poorly controlled morphologies like Nafion, and are typically not on par with Nafion’s performance.
