Optimizing Fuel Cell Catalyst Stability upon Integration with Reforming

OFICeR – G5729

Towards stable graphene-based PEMFC catalyst support
for autonomous operation

Goals

Stable and affordable PEM-FC will allow the reliable autonomous supply of electricity by replacing a typical high-surface-area with graphene-based carbon by decreasing the Pt content

Stability of PEM-FC catalyst will be addressed: by feedback between synthesis, modeling, and advanced characterization

New Pt-modified-graphene and non-Pt-modified-graphene composites will be developed and tested at relevant conditions (diesel reformer)

Methodology

OFICeR combines modern synthetic procedures, state-of-the-art theoretical calculations, and some of the most advanced materials characterization tools in order to reach project goals.

 

Implementation
