“…The peaks at 2 values of 39.7 and 43.9° indexed to the (111) and (200) facets, respectively, can be assigned to the face-centered cubic crystalline structure of Pd [8,11]. The shift to lower angles is caused by lattice expansion due to nanosized particles and alloying with Ni and Bi [7,13,15]. The nanocrystalline nature is further indicated by the broad peak shape.…”

“…The peaks between 1.2 to 1.5 V vs. RHE describe the oxidation of Ni(OH) 2 to NiOOH and the corresponding reduction of NiOOH to Ni(OH) 2 (Figure 3a) [19]. The peaks in the cathodic scan between 0.9 V and 0.6 V vs. RHE are associated with Bi oxide reduction and the reduction of PdO to Pd [7]. A comparison with the CV (Figure 3b) of the commercial Pd/C shows that the hydrogen ad/absorption peaks for the PdNiBi/rGO are suppressed, which can be attributed to the presence of Bi [18,20,21].…”

“…The PdNiBi/rGO (40 wt.% of metal and 60 wt.% of carbon support) composite catalyst was synthesized according to the modified instant reduction method [7,15]. The as-prepared rGO was dispersed in ultrapure water under a nitrogen atmosphere and ice cooling using an ultrasonic probe (Hilscher, UP440s).…”

“…To overcome this problem, alloying Pd with oxophilic co-catalyst elements such as Ni, Bi, Cd or Co is very effective for increasing the EOR activity and stability due to enhanced -OHadsorption while reducing costs [7][8][9][10][11]. Deposition of the metal nanoparticles on a suitable support material offers another possibility to increase the efficiency of such catalysts, as it features the capability to control the size, distribution, morphology and stability of the immobilized particles.…”

The sluggish kinetics of the ethanol oxidation reaction (EOR) and the related development of low-cost, highly active and stable anode catalysts still remains the major challenge in alkaline direct ethanol fuel cells (ADEFCs). In this respect, we synthesized a PdNiBi nanocatalyst on reduced graphene oxide (rGO) via a facile synthesis method. The prepared composite catalyst was physicochemically characterized by SEM, STEM, EDX, ICP-OES and XRD to analyze the morphology, particle distribution and size, elemental composition and structure. The electrochemical activity and stability towards EOR in alkaline media were examined using the thin-film rotating disk electrode technique. The results reveal well-dispersed and strongly anchored nanoparticles on the rGO support, providing abundant active sites. The PdNiBi/rGO presents a higher EOR activity and stability compared to a commercial Pd/C ascribed to a high ECSA and synergistic effects between Pd, Ni and Bi and the rGO material. These findings suggest PdNiBi/rGO as a promising anode catalyst in ADEFC applications.

In recent years, there has been considerable interest in anion exchange membrane fuel cells (AEMFCs) as part of fuel cell technology. Anion exchange membranes (AEMs) provide a significant contribution to the development of fuel cells, particularly in terms of performance and efficiency. Polymer composite membranes composed of quaternary ammonium poly(vinyl alcohol) (QPVA) as electrospun nanofiber mats and a combination of QPVA and poly(diallyldimethylammonium chloride) (PDDA) as interfiber voids matrix filler were prepared and characterized. The influence of various QPVA/PDDA mass ratios as matrix fillers on anion exchange membranes and alkaline fuel cells was evaluated. The structural, morphological, mechanical, and thermal properties of AEMs were characterized. To evaluate the AEMs’ performances, several measurements comprise swelling properties, ion exchange capacity (IEC), hydroxide conductivity (σ), alkaline stability, and single-cell test in fuel cells. The eQP-PDD0.5 acquired the highest hydroxide conductivity of 43.67 ms cm−1 at 80 °C. The tensile strength of the membranes rose with the incorporation of the filler matrix, with TS ranging from 23.18 to 24.95 Mpa. The peak power density and current density of 24 mW cm−2 and 131 mA cm−2 were achieved with single cells comprising eQP-PDD0.5 membrane at 57 °C.
