In the present study, various commercial carbon black materials like Vulcan XC72, Black Pearl 2000, and Regal 330 were used as supporting material for polymer electrolyte membrane fuel cell (PEMFC) electrocatalysts. A promising carbon material exhibiting hollow core mesoporous shell (HCMS) structure was synthesized by the template replication of the silica spheres with solid core and mesoporous shell structure. Two carbon supports with similar pore texture were prepared by the injection of two different carbon precursors. 20 wt% Pt/C electrocatalysts were synthesized by microwave irradiation method as the cathode electrode for PEMFC. Ex situ characterization of the electrocatalysts was performed by N-2 adsorption analysis, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), and transmission electron microscopy (TEM). Electrochemical characterization of the electrocatalysts was conducted by cyclic voltammetry (CV) analysis. Effect of different carbon supports on the cathode performance was investigated in a single cell H-2/O-2 PEMFC. Fuel cell performance tests and additional ex situ characterizations showed that HCMS carbons exhibit good support characteristics with improved single cell performance. For the cathode electrode kinetics, promising fuel cell performance results were obtained as compared to the commercial carbon blacks. (C) 2009 Professor T. Nejat Veziroglu.

Pt-based electrocatalysts for polymer electrolyte membrane fuel cells prepared by supercritical deposition technique Bayrakceken, Ayse; Smirnova, Alevtina; Kitkamthorn, Usanee; Aindow, Mark; Turker, Lemi; Eroğlu, İnci; Erkey, Can (Elsevier BV, 2008-05-01) Pt-based electrocatalysts were prepared on different carbon supports which are multiwall carbon nanotubes (MWCNTs), Vulcan XC 72R (VXR) and black pearl 2000 (BP2000) using a supercritical carbon dioxide (ScCO2) deposition technique. These catalysts were characterized by using X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and cyclic voltammetry (CV). XRD and HRTEM results demonstrated that the ScCO2 deposition technique enables a high surface area metal phase to be deposit...
PEM fuel cell degradation effects on the performance of a stand-alone solar energy system ÖZDEN, Ender; Tarı, İlker (Elsevier BV, 2017-05-04) After comparing fresh and degraded performances of Polymer Electrolyte Membrane (PEM) based components of a hydrogen cycle with the help of computational fluid dynamics simulations, recently established stand-alone solar energy system producing hydrogen for energy storage is investigated focusing on the effects of degradation of fuel cells on the overall performance of the system. A complete model of the system has been developed using TRNSYS, and a degraded PEM Fuel Cell Subsystem has been incorporated int...
Mo doping of layered Li (NixMnyCo1-x-y-zMz)O-2 cathode materials for lithium-ion batteries PİŞKİN, BERKE; Uygur, Cansu Savas; Aydınol, Mehmet Kadri (Wiley, 2018-10-10) We systematically investigated the effects of Mo doping on the structure, morphology, and the electrochemical performance of Li (NixMnyCo1-x-y-zMz)O-2 (NMC) cathode materials for Li-ion batteries. Layered NMC cathodes were synthesized with the ratio of 111, 622, and 226 via spray pyrolysis yielding submicron-sized aggregates in the shape of hollow spherical particles. We performed X-ray diffraction analyses to determine the present phases and the ordering in structure. X-ray diffraction pattern of Mo-doped ...
Morphology effect on electrochemical properties of doped (W and Mo) 622NMC, 111NMC, and 226NMC cathode materials Pişkin, B.; Uygur, Cansu Savaş; Aydınol, Mehmet Kadri (Elsevier BV, 2020-03-01) An investigation was carried out on layered Li(NixMnyCo1-x-y)O-2 (NMC) cathode active materials for Li-ion batteries to determine the effect of morphology on their electrochemical performances. The NMC active materials were doped with Mo or W (2 wt%) in the study. Doped NMC cathodes with a ratio of 111, 622 and 226 (NiMnCo) were synthesized by spray pyrolysis which yielded aggregates were submicron size. A systematic investigation was performed, and two distinct morphology types were identified in active ma...
Glass fiber reinforced sealants for solid oxide fuel cells Timurkutluk, Bora; Altan, Tolga; Celik, Selahattin; Timurkutluk, Cigdem; PALACI, Yüksel (Elsevier BV, 2019-07-05) Novel sealants for solid oxide fuel cells are developed by addition of glass fiber into glass ceramic as a reinforcement material. Various sealants including three different fiberglass types and four different structural designs are fabricated. The mechanical and sealing performances of the sealants are investigated via tensile and short stack leakage tests, respectively. The tensile tests reveal that the fracture strength of the sealants varies depending on the type and number of the glass fiber used. In g...
