- Journal:Carbon
- Summary:In recent years, the oxygen reduction reaction (ORR) performance of N-doped carbon catalysts has made
great progress and is now comparable to that of commercial Pt/C. However, the rich porous features of Ndoped carbon catalysts give them a very low bulk density, which leads to problems in oxygen mass
transfer due to water flooding when they are used as the cathode in fuel cells. Herein, a controllable
mesoporous surface of nitrogen-doped yolk-shelled carbon spheres (N-YS-CS) with an extremely regular
particle size was synthesized. The mesopores of the N-YS-CS effectively store the hydrophobic agent and
form robust hydrophobic tunnels within the close-packed N-YS-CS units, forming an excellent structure
for mass transfer at the cathode. This elaborately constructed hydrophobic cathode structure has a larger
triple-phase interface than traditional carbon paper in an electrolyte-penetration-type direct methanol
fuel cell (DMFC) with a polymer fiber membrane (PFM), and delivers a high power density (55 and
142 mW cm2 at 25 C and 60 C, respectively) and discharge stability (a run time of over 210 h). - Co-author:C.Shu, B.Song, X.Wei, Y. Liu, Q. Tan, S.Chong,Y. Chen*, X. Yang, W. Yang, Y. Liu
