Non-thermal Plasma-modified Carbon Carrying Sn-based Ternary Nanocatalyst for High-Performance Direct Dimethyl Ether Fuel Cells
Original language description
A Vulcan XC72 carbon-supported Sn-based ternary metal catalyst (Pt3Pd3Sn2/C) was reported to have yielded the highest specific power density (90 mW mg-1 PGM) as compared to other catalysts tested for direct DME fuel cells. However, the micropores present in Vulcan XC72 limit fuel utilization by causing Pt agglomeration. Vulcan XC72 composed of non-graphitized carbon species is also prone to corrosion. Therefore, in this study, carbon supports such as multi-walled carbon nanotubes (MWCNT), black pearl 2000 (BP2000), and their cold N2 plasma-treated counterparts were tested to further enhance the activity of the catalyst and systematically describe the comparative advantages over the Vulcan XC-72 carbon. Electroanalytical tests show that Pt3Pd3Sn2/BP2000 exhibited excellent performance in terms of electrochemical active surface area (ECSA), peak current density (jp), and DME oxidation charge (Qoxi). A beneficial effect of plasma activation on the activity was observed only in the case of MWCNT while having no or negative effect on the other carbons. Laboratory fuel cell test indicated that Pt3Pd3Sn2 nanoparticles supported on optimized binary carbon support containing 75% plasma-activated MWCNT and 25% BP2000 (Pt3Pd3Sn2/75M25B) provided the highest reported power density of 117 mW mg-1 PGM at 70 °C fuel cell temperature and ambient pressure.
