Plasma based platinum nanoaggregates deposited on carbon nanofibers improve fuel cell efficiency

Caillard, Amaël; Charles, Christine; Boswell, Rod; Brault, Pascal; Coutanceau, Christophe

Description

Improved platinum catalytic utilization has been achieved by creating an open support structure based on aligned carbon nanofibers (CNFs) attached to carbon loaded carbon cloth electrodes [known as gas diffusion layer (GDL)]. The nickel catalyst used to initiate the CNFs growth; the CNFs themselves and the 5nm Pt nanoaggregates were deposited sequentially in the same low pressure plasma reactor. This oriented catalyst structure was incorporated into a membraneelectrode assembly and tested with...[Show more]
