Abstract
|
The
limited stability of fuel cell cathode catalysts causes a significant loss of
operational cell voltage with commercial Pt-based catalysts, which hinders
the wider commercialization of fuel cell technologies. Authors explain the
beneficial effects of a highly rigid and porous polymer of intrinsic
microporosity in accelerated catalyst corrosion experiments.
Porous films of PIM-EA-TB offer an effective protective matrix for the prevention of Pt/C catalyst corrosion without impeding flux of reagents. The results of electrochemical cycling tests show that the PIM-EA-TB protected Pt/C exhibit a significantly enhanced durability as compared to a conventional Pt/C catalyst. |
