An Experimental Study on the Placement of Reference Electrodes in Alkaline Polymer Electrolyte Membrane Fuel Cells
The ability to accurately measure separate in situ anode and cathode overpotentials and impedance responses is still a source of debate when investigating fuel cells of planar configuration containing < 100 μm thickness solid electrolytes and when using the common three electrode arrangement. The results obtained in this study indicate that the overpotentials and impedances of the anode and cat...
متن کاملNumerical analysis of reactant transport in the novel tubular polymer electrolyte membrane fuel cells
In present work, numerical analysis of three novel PEM fuel cells with tubular geometry was conducted. Tree different cross section was considered for PEM, namely: circular, square and triangular. Similar boundary and operational conditions is applied for all the geometries. At first, the obtained polarization curve for basic architecture fuel cells was validated with experimental data and then...
متن کاملStudy of Alkaline Electrodes for Hybrid Polymer Electrolyte Fuel Cells
Hybrid polymer electrolyte fuel cells combine a proton exchange membrane PEM and anion exchange membrane AEM and exhibit unique advantages. The electrochemical performance and current limitations of a hybrid cell with an alkaline electrode fabricated on a Nafion membrane was characterized at 70°C as a function of relative humidity. To separate the individual characteristics of the AEM anode and...
متن کاملCharacterizing Electrode-Level Oxygen Transport in Polymer Electrolyte Fuel Cells
Polymer electrolyte fuel cells (PEFCs) are a promising technology for environmentally friendly automobiles, among other applications. However, performance losses due to oxygen transport hindrances in the PEFC’s cathode continue to be an issue in widespread commercialization. This dissertation focuses on the transport of oxygen through the thickness of the PEFC cathode, and the effect of the cat...
متن کاملFabrication of bifunctional membrane electrode assemblies for unitised regenerative polymer electrolyte fuel cells
Introduction: The conversion and storage of energy with a high efficiency, especially a high specific energy, will be an important factor in future energy storage technologies. The relatively simple possibility to store hydrogen and oxygen with high specific energy combined with high energy conversion efficiency in fuel cells and electrolyser presents an opportunity for the use of polymer elect...
