Microporous layers (MPLs) were prepared with different hydrophobic polymers to establish water management in polymer electrolyte membrane (PEM) fuel cells. Besides conventionally used polymers polytetrafluoroethylene (PTFE) and fluorinated ethylene propylene (FEP), two different molecular weights (MW) of polydimethylsiloxane (PDMS) polymer were used as hydrophobic materials in MPL. Membrane electrode assemblies (MEAs) having MPLs with low MW PDMS polymer exhibited the best fuel cell performance compared to the PTFE and FEP based ones. Thus it is concluded that PDMS polymer has a great potential to be used as hydrophobic material for MPL to reduce flooding phenomena in PEM fuel cell. (C) 2017 Hydrogen Energy Publications LLC.

Electrocatalyst development and modeling of nonisothermal two-phase flow for PEM fuel cells Fıçıcılar, Berker; Eroğlu, İnci; Department of Chemical Engineering (2011) A macro-homogeneous, nonisothermal, two-phase, and steady state mathematical model is developed to investigate water and thermal management in polymer electrolyte membrane (PEM) fuel cells. An original two-phase energy balance approach is used to catch the thermal transport phenomena in cases when there is a signi cant temperature di erence between the fuel cell temperature and the reactants inlet temperatures like during cold start-up. Model considers in depth electrode kinetics for both anode and cathode ...
PEM fuel cell short stack performances of silica doped nanocomposite membranes DEVRİM, YILSER; Devrim, Huseyin (2015-06-29) In this study, an air-cooled Proton Exchange Membrane Fuel Cell (PEMFC) short stack with Nafion/Silica nanocomposite membrane was designed and fabricated for net 100 W net power output to improve the stack performance at low relative humidity conditions. Composite membrane was prepared by solution casting method. Gas Diffusion Electrodes (GDE's) were produced by ultrasonic spray coating technique. Short stack design was based on electrochemical data obtained at 0.60 V was 0.45 A/cm(2) from performance tests...
High performance PEM fuel cell catalyst layers with hydrophobic channels Avcioglu, Gokce S.; FIÇICILAR, BERKER; BAYRAKÇEKEN YURTCAN, Ayşe; Eroğlu, İnci (2015-06-29) Polymer electrolyte membrane fuel cell performance has been enhanced with efficient water management by modification of the structure of the catalyst layer. Polytetrafluoroethylene (PTFE) was added to the catalyst layer structure by using two-step catalyst ink preparation method. Physical and electrochemical characterization of catalyst layers with hydrophobic nanoparticles were investigated via TGA-DTA, XRD, nitrogen physisorption, SEM, TEM, EDX analysis, and cyclic voltammetry technique. In addition, perf...
Numerical Investigation of thermal management of Solid Oxide Fuel Cells by flow arrangement Şen, Fırat; Tarı, İlker (null; 2015-05-29) SolidOxide Fuel Cells (SOFCs) are electrochemical cells working at high temperatures. One of the important problems in planar SOFC designs is the non-uniformtemperature distribution on the plane of the cell due to the waste heat produced by electrochemical reactions. Another important problem of SOFCs is the low fuel utilization ratio. In this study, the effect of the flow arrangement on the temperature distribution, which causes the thermal stresses, and the met...
Influence of FEP nanoparticles in catalyst layer on water management and performance of PEM fuel cell with high Pt loading Avcioglu, Gokce S.; FIÇICILAR, BERKER; Eroğlu, İnci (2017-01-05) In this study, fluorinated ethylene propylene (FEP) nanoparticles were added to catalyst layer (CL) to facilitate excess water removal from the triple phase boundary in high Pt loading (1.2 mg/cm(2)) proton exchange membrane fuel cell (PEMFC) electrodes. The loading of PEP in the catalyst ink was varied from zero to 30 weight percentage. High-performance electrodes for anode and cathode were prepared by ultrasonic spray coating technique with a commercial catalyst containing 70 wt. % Pt on carbon. Different...
