Catalytic performance of acid-treated multi-walled carbon nanotube-supported platinum catalyst for PEM fuel cells

“…This is presumably due to the smaller Pt particle size and higher Pt active area of Pt/C catalyst than those of the Pt/MWCNT catalysts. Acceleration tests were conducted to compare the durability of prepared MEAs using a reverse voltage operation generated by fuel starvation conditions [28]. As shown in Fig.…”

“…The first set of MWCNT (CM-95, purity > 95%, Hanwha Nanotech Co.) supports were pretreated for 4 h at 25 8C in a solution of sulfuric acid, while the other set was treated for 36 h at 110 8C in a solution of nitric acid. The Pt/MWCNT (4 h, 25 8C) and Pt/MWCNT (36 h, 110 8C) catalysts were synthesized using treated MWCNTs as catalyst supports via a polyol process described in our previous work [28].…”

“…In this report, we systemically studied the effect of surface functional groups of MWCNTs on the Pt dispersion, initial cell performance and long-term durability at the accelerated cell degradation conditions [28]. We found that more functional groups in MWCNTs improved initial Pt dispersion but deteriorated durability due to the weak adhesion between Pt and MWCNTs.…”
