The aim of this study is to synthesize mesoporous carbon supports and prepare their corresponding electrocatalysts with microwave irradiation method and also increasing the Pt loading over the carbon support by using some additional reducing agents. Pt loadings on hollow core mesoporous shell (HCMS) and commercial Vulcan XC72 carbon supports up to 34% and 44%, respectively, were achieved via polyol process with microwave irradiation method. When hydrazine or sodium borohydride was used in addition to ethylene glycol, Pt loading over the HCMS carbon support was increased. Characterization of the prepared electrocatalysts was performed by ex situ (BET, XRD, SEM, TGA and Cyclic Voltammetry) and in situ (PEM fuel cell tests) analysis. PEM fuel cell performance tests showed that 44% Pt/Vulcan XC72 and 28% Pt/HCMS electrocatalysts exhibited improved fuel cell performances. The results revealed that as the Pt loading increased PEM fuel cell performance was also increased. Copyright (C) 2011, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.

Polymer-immobilized palladium supported on TiO2 (Pd-PVB-TiO2) as highly active and reusable catalyst for hydrogen generation from the hydrolysis of unstirred ammonia-borane solution Rakap, Murat; Kalu, Egwu Eric; Özkar, Saim (Elsevier BV, 2011-01-01) Herein we report the preparation, characterization and the catalytic use of the polymer-immobilized palladium catalyst supported on TiO2 (Pd-PVB-TiO2) in the hydrolysis of unstirred ammonia-borane solution. The polymer-immobilized palladium catalyst is stable enough to be isolated as solid materials and characterized by XRD, SM, and EDX. The immobilized palladium catalyst supported on TiO2 is found highly active, isolable, and reusable in the hydrolysis of unstirred ammonia-borane even at low concentrations...
Experimental investigation of CO tolerance in high temperature PEM fuel cells DEVRİM, YILSER; Albostan, Ayhan; Devrim, Huseyin (Elsevier BV, 2018-10-04) In the present work, the effect of operating a high temperature proton exchange membrane fuel cell (HT-PEMFC) with different reactant gases has been investigated throughout performance tests. Also, the effects of temperature on the performance of a HT-PEMFC were analyzed at varying temperatures, ranging from 140 degrees C to 200 degrees C. Increasing the operating temperature of the cell increases the performance of the HT-PEMFC. The optimum operating temperature was determined to be 160 degrees C due to th...
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...
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...
Effects of membrane electrode assembly components on proton exchange membrane fuel cell performance Bayrakceken, Ayse; Erkan, Serdar; Turker, Lemi; Eroğlu, İnci (Elsevier BV, 2008-01-01) The objective of this study is to determine the effects of various factors on the performance of proton exchange membrane (PEM) fuel cell. These factors are membrane thickness, hot-pressing conditions of the gas diffusion layer (GDL) either onto the membrane or membrane electrode assembly (MEA) and Teflon:carbon ratio in the GDL on PEM fuel cell performance. Homemade five-layer and commercial three-layer MEAs were used in the experiments. Nafion (R) 112 and 115 which have nominal thicknesses of 50 and 125 m...
