Abstract

Vapor grown carbon fibers (VGCF) by Showa Denko are highly graphitized carbon nanofibers. VGCFs show superior thermal stability and corrosion resistance over traditional carbon black supports. The performance and durability of the synthesized catalysts have been evaluated and compared to carbon black supported catalyst. The test methods described here include automotive drive cycle testing in multi-single cell unit as well as accelerated in situ carbon degradation routine with CO2 monitoring from cathode exhaust gases. The Pt/VGCF catalyst shows significantly lower carbon corrosion than commercial carbon black supported Pt catalyst in simulated and actual start/stop cycling.
