Numerical 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 کاملHigh-Peak-Power Polymer Electrolyte Membrane Fuel Cells
A polymer electrolyte membrane fuel cell with amorphous hydrated ruthenium dioxide (RuO2 " xH2O) supercapacitative sublayers inserted between the electrocatalyst layers and the Nafion membrane was fabricated to enhance the cell’s pulse power output. RuO2 " xH2O material showed a high capacitance ~ca. 230 F/g! and allowed a much higher pulse power output, which was demonstrated by cyclic voltamm...
متن کاملDrops, Slugs, and Flooding in Polymer Electrolyte Membrane Fuel Cells
The process of flooding has been examined with a single-channel fuel cell that permits direct observation of liquid water motion and local current density. As product water flows through the largest pores in the hydrophobic GDL, drops detach from the surface, aggregate, and form slugs. Flooding in polymer electrolyte membrane (PEM) fuel cells occurs when liquid water slugs accumulate in the gas...
متن کاملMaterials and characterization techniques for high-temperature polymer electrolyte membrane fuel cells
The performance of high-temperature polymer electrolyte membrane fuel cells (HT-PEMFC) is critically dependent on the selection of materials and optimization of individual components. A conventional high-temperature membrane electrode assembly (HT-MEA) primarily consists of a polybenzimidazole (PBI)-type membrane containing phosphoric acid and two gas diffusion electrodes (GDE), the anode and t...
متن کاملAl2O3 Disk Supported Si3N4 Hydrogen Purification Membrane for Low Temperature Polymer Electrolyte Membrane Fuel Cells
Reformate gas, a commonly employed fuel for polymer electrolyte membrane fuel cells (PEMFCs), contains carbon monoxide, which poisons Pt-containing anodes in such devices. A novel, low-cost mesoporous Si3N4 selective gas separation material was tested as a hydrogen clean-up membrane to remove CO from simulated feed gas to single-cell PEMFC, employing Nafion as the polymer electrolyte membrane. ...
