Highly permeable perfluorinated sulfonic acid ionomers for improved electrochemical devices: insights into structure–property relationships
Summary
A new perfluorinated sulfonic acid ionomer whose glassy amorphous backbone (PFMMD) replaces the PTFE matrix of commercial materials. It limits swelling of the ionic domains and disrupts crystallinity, trading a slight loss of proton conductivity for much higher gas permeability, which could improve fuel-cell electrodes with low platinum loading when used as catalyst binder.
