“…The onset potential was 200 mV lower and the peak current density was four times higher for ethanol oxidation on Pd-Ni/CNF compared with that of Pd/C. Shen et al [182] synthesized carbon-supported PdNi catalysts for the ethanol oxidation reaction in alkaline direct ethanol fuel cells. The Pd2Ni3/C catalyst exhibited higher activity and stability for the EOR in an alkaline medium than that on Pd/C catalyst.…”

“…The Tokuyama company in Japan is one of the pioneers in the anion-exchange membrane and most reported work were using their membranes. In recent years, Zhao's group [132,182,190,191] has done most of the work on the anion-exchange membrane direct ethanol fuel cells (AEMDEFCs). Other researchers such as Antolini [192] and Bambagioni [193] also tested the performance of the AEMDEFC, the results of these groups were compared in Figure 8.…”

“…Ruoshi et al, published that, the addition of Ni to Pd alloy decreases the particle size, which would result in the increase of electroactive surface areas [36]. Shen et al [37] have reduced PdNi catalysts in different atomic ratios on carbon surface using NaBH 4 as a reductant. They had average Pd particle size of 3-3.2 nm.…”

The modified polyol reduction method was used to prepare a carbon-supported bimetallic PdNi nanoalloys (BMNAs). The prepared catalyst was characterized using X-ray diffraction and transmission electron microscopy. The obtained data indicated that, the average particle size of the alloys in the range & 20-50 nm. The morphology structure shows uniformly distributed particles on the supported carbon surface. The catalytic activity of the compounds for oxygen reduction reaction was investigated by cyclic voltammetry and electrochemical polarization measurements in rotating disk electrodes. As a function of time and calcination temperature, the improved activity and stability were obtained at 300°C for 3 h.

Application of fuel cell to produce renewable energy for commercial purpose is limited by the high cost of Pt based electrode materials. Development of inexpensive, high energetic electrode is the need of the hour to produce pollution free energy using bio-fuel through a fuel cell. Ni-Cu and Ni-CeO 2 -Cu electrode materials, electro synthesized by pulse current have been developed. The surface morphology of the electrode materials is controlled by different deposition parameters in order to produce a high current from the electro-oxidation of the fuel, the ethanol. The developed materials are electrochemically characterized by Cyclic Voltammetry (CV), Chronoamperometry (CA) and Potentiodynamic polarization tests. The results confirm that the high current is due to their enhanced catalytic properties viz. high exchange current density (i 0 ), low polarization resistance (R p ) and low impedance. It is worthwhile to mention here that the addition of CeO 2 to Ni-Cu has outperformed Pt as far as the high electro catalytic properties are concerned; the exchange current density is about eight times higher than the same on Pt surface. The morphology of the electrode surface examined by SEM and FESEM exhibits that the grains are narrow and sub spherical with 3D surface, containing vacancies in between the elongated grains. The fact has enhanced more surface area for electro oxidation of the fuel, giving rise to an increase in current. Presence of Ni, CeO ,and Cu is confirmed by the XRD and EDXS. Fuel cell fabricated with Ni-CeO 2 -Cu material electrode is expected to produce clean electrical energy at cheaper rates than conventional one, using bio fuel the derived from biomass.
