Performance comparison of low-temperature direct alcohol fuel cells with different anode catalysts

“…Different from Ru, the addition of which enhances indubitably methanol electro-oxidation on Pt regardless of the preparation mode [5,[25][26][27][28], the effect of Sn on Pt activity for methanol electro-oxidation is controversial in previous papers, from huge enhancement [29][30][31][32] to lower activity than pure Pt even inhibition [33][34][35], depending greatly on PtSn catalyst preparation procedure. As shown in Fig.…”

Kinetics of CH3OH oxidation on PtRu/C studied by impedance and CO stripping voltammetry

“…Binary PtRu/C is a promising anode catalyst for use in the direct-methanol fuel cell (DMFC) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

Electrochemical Analysis of Direct Methanol Fuel Cells for Low Temperature Operation

“…TEM analysis was carried out by a Philips CM12 microscope. The electrodes were prepared according to the procedure described in a previous paper [12]; they consisted of carbon cloth, diffusion and catalytic layers. An 85% Pt-Ru alloy (1:1)/C catalyst was employed at the anode; whereas, a 60% Pt/C catalyst was utilized for cathode fabrication.…”

“…In order to reduce ohmic drop, mass transport and manufacturing problems deriving by the use of thick electrodes, the present DMFC catalysts for low temperature applications are usually unsupported Pt and Pt-Ru alloys [10][11][12]. Yet, the presence of catalyst agglomeration effects in unsupported catalysts significantly limits their utilisation in polymer electrolyte fuel cell systems.…”
