Carbon nanotubes as support for cathode catalyst of a direct methanol fuel cell

Pt-based anode catalysts for direct ethanol fuel cells

“…The membrane electrode assembles (MEAs) were fabricated according to the method described in previous works [19,20,22]. The anode contained the in-house carbon-supported Pt-based catalysts with a Pt loading of 1.33 mg/cm 2 (except the case when pure Pt/C was used as anode catalyst where the platinum loading was 2.0 mg/cm 2 ) and the cathode contained commercial Pt/C catalyst (20 wt.%) purchased from Johnson Matthey with a Pt loading of 1.0 mg/cm 2 , which was kept identical in all the MEAs.…”

“…Based on our previous exploratory works [17][18][19][20], several Pt-based binary and ternary metallic anode catalysts were studied by cyclic voltammetry and tested as anodes in single direct ethanol fuel cells at lower temperatures in order to identify the most appropriate. In spite of many factors affecting its performance, the single fuel cell is still considered as a very effective and ultimate reactor to evaluate electrocatalysts when other operation parameters are well defined.…”

Synthesis and characterization of carbon black supported Pt–Ru alloy as a model catalyst for fuel cells

“…An atomic ratio of Pt to Ru of 1:1 was found to be the best chemical composition for the most CO-tolerant anode catalyst [10]. Many papers dealing with the synthesis of this kind of catalysts using co-impregnation and colloidal methods can be found in the recent literature [11][12][13][14]. But to our knowledge, little attention has been paid to the characterization of carbon supported Pt-Ru catalysts [15].…”

PtCo alloy nanoparticles supported on graphene nanosheets with high performance for methanol oxidation

“…In view of the unique structure of graphene, this two-dimensional (2D) carbon material has found potential applications as a heterogeneous catalyst support in DMFCs [28,29]. It is well known that carbon nanotubes (CNTs) have been extensively studied as supports for the dispersion of Pt nanoparticles owing to their fascinating properties [30][31][32][33]. In comparison with CNTs, graphene possesses similar stable physical properties but larger surface areas, which can be considered as an unrolled CNT [34,35].…”
