SUMMARY The effects of both anode and cathode perforated flow field configurations on proton exchange membrane fuel cell performance are studied herein through electrochemical polarization techniques, electrochemical impedance spectroscopy, and cyclic voltammetry. The results demonstrate that serpentine flow field configuration in both anodes and cathodes is the best arrangement for cell performance (serpentine/serpentine, perforated/perforated, and serpentine/perforated). An electrochemical impedance spectroscopy examination shows that the serpentine/serpentine flow plate configuration results in a significant reduction in charge transfer resistance in a high current density (low voltage) regime. It further indicates that in a serpentine/serpentine flow pattern, a maximum electrochemical area is obtained with a higher Pt utilization of about 70% and is secured with full hydration at a cell temperature of 80°C. Finally, energy and exergy efficiencies analyses were also made. Data have been extracted and presented. Copyright © 2013 John Wiley & Sons, Ltd.

“…As expected, commonly reported diffraction peaks were observed for Pt/C alloy materials. 27,33,45 The electrocatalytic activity of the synthesized catalysts was determined and compared using cyclic voltammetry (CV) (Solatron SI1257). and the corresponding voltammograms were obtained by rotating humidified H 2 and Ar fed in the anode and cathode chambers between V 0 and 1.2 of the cathode at 20 mV −1 against a Standard Hydrogen Electrode (SHE) with pure, respectively.…”

This study aims to develop a high-performance Pt/C catalyst for the cathode and anode parts of a modified Proton exchange membrane (PEM) fuel cell in nitrogen and argon gases at different microwave radiation powers. The pure and modified forms of the synthesized Pt/C catalysts were characterised using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD results revealed that the crystal structure of the modified Pt/C catalyst was perfect and that the particle size of the catalytic material grew significantly as a consequence of the modification. Furthermore, the durability of PEM fuel cell electrocatalysts was investigated using the cyclic voltammetry (CV) technique. The experimental results indicated that microwave radiation had a significant effect on the particle size of the Pt/C catalyst. Additionally, the modified Pt/C catalyst exhibited a decreased activation potential loss and increased the cathode and anode power density values by 34% and 47%, respectively, compared to the Pt/C catalyst.

“…To overcome limitations and to further improve the effectiveness of catalysts, many researchers have focused on the development of material-supported Pt catalysts. In this regard, carbon nanotubes (CNTs) [6] and bacterial cellulose (BC) [7] are of interest in the development of a novel hybrid membrane catalyst for a wide range of applications.…”

Catalytic hydrogenation of n-butene with nanosized Pt/NBCNT hybrid membranes reinforced with bacterial cellulose

One of the main challenges in the field of heterogeneous catalysis is the involvement of thin solid films and membranes and their application in flow systems. In this regard, we report here the application of self-supported bacterial cellulose (BC) reinforced nanosized platinum (Pt)/N-doped bamboo-like carbon nanotube (NBCNT) hybrid catalyst membrane with a thickness of 35 ± 5 µm in the hydrogenation of n-butene. To synthetized the BC-NBCNT/Pt nanohybrid membrane catalyst a simple impregnation route was applied in a two-step process. As-prepared material was tested in a continuous flow system and the conversion was followed directly by using Fourier transform infrared spectroscopy. Furthermore, the fabricated films were characterized by scanning electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy and specific surface area measurement (Brunauer–Emmett–Teller). Hydrogenation performance was studied on both single and double films. Results revealed that 97% conversion of n-butene can be achieved using these bacterial cellulose reinforced hybrid membranes.
