Electrodeposited palladium nanostructure as novel anode for direct formic acid fuel cell

Recent Development of Pd-Based Electrocatalysts for Proton Exchange Membrane Fuel Cells

“…The single fuel cell performance of the different catalysts was selectively summarized in Figure 6. Meng et al [118] designed a novel MEA structure for DFAFCs where Pd nanothorns were directly electrodeposited onto the carbon paper to form the anode catalyst layer. The novel MEA provided 2.4 times higher peak power density than that of the conventional MEA.…”

Effect of the structure of Ni nanoparticles on the electrocatalytic activity of Ni@Pd/C for formic acid oxidation

“…3, the spectrum showed only two asymmetric Pd peaks assigned to Pd 3d 5/2 and Pd 3d 3/2 having a binding energy of 341 eV and 336 eV, typical of Pd metal. The peaks of Pd 3d 5/2 at around 342 eV and Pd 3d 3/2 at 337 eV are assigned to Pd(II) in PdO [30]. Comparison of binding energies of Pd 3d 5/2 and Pd 3d 3/2 for Ni c @Pd/C and Ni a @Pd/C is presented in Table 1.…”

Sensing Behavior of Room Temperature Amperometric H2Sensor with Pd Electrodeposited from Ionic Liquid Electrolyte as Sensing Electrode

“…Pd electrodeposition in aqueous electrolyte and its characterization has already been studied extensively by Hui Meng 34 et al, Debasis The micrographs indicate that the surface coverage of Pd increases with increasing applied potentials. 38 Surface coverage is insufficient at −0.8 V and −0.9 V while at −1.1 V non uniform deposit with large lumps of Pd is observed.…”

“…34,[45][46][47] Particle agglomeration is expected to be significantly reduced in the case of ionic liquid electrolyte compared to aqueous electrolytes since it acts a surfactant also during deposition. Electrodeposition of electro-catalyst from aqueous medium has disadvantage of poor adherence of the deposit onto the substrate due to H 2 evolution.…”
