Some research studies reported a series of advantages regarding the effect of ratio w/a >1 on the PEMFC performance, like an enhanced mechanical support for membrane and Gas Diffusion Layer (GDL), higher water content in the membrane, improved ion conductivity of the membrane, improved heat transfer from membrane to GDL, uniform distribution of the current density and temperature across the membrane and improved performance at high current densities [17, 18].
Increased current densities achieved with NaOH modification were most likely due to the electrode surface becoming more hydrophilic, which would create a more favorable environment for the ORR taking place at the electrode surface.
To account for the random gating of sodium and potassium channels, the ionic current densities [I.sub.Na] = [g.sub.Na] (V-[E.sub.Na]) and [I.sub.K] = [g.sub.K](V - [E.sub.K]) were calculated using a channel-state-tracking algorithm [27, 28] where Markov chains [27, 29] modeled independent gating particles belonging to each ionic channel.
Boundary conditions were specified as input normal current densities ([J.sub.input]) of 0.4mA/[m.sup.2] applied to anode electrodes (T7, Fpz), while cathode electrodes (T8 or Oz, respectively) were set to ground voltage.
This was done by varying pH (2, 4, 6, and 8) against current densities (0.5, 1.0, 1.5, 2.0, and 3.0A) at 60 minutes and 60[degrees]C.
At higher current densities, the heat generated is higher than at the lower current densities.
Featuring a , these platinum-clad mesh anodes provide a more uniform current distribution with lower operating current densities. Key Features:
In the present study, the influence of binder types, consisting of sole OPC and blending cement with GGBS, on the removal of initially contained chlorides from the inside of steel reinforced mortars and the resultant corrosion rehabilitation was evaluated by measuring polarization resistance and corrosion potential under variation of cathodic current densities between 250 and 750 mA/[m.sup.2].
Suppose there is an infinite neodymium iron boron permanent magnet; the external magnetic field is parallel to the surface in the direction of the z-axis; the vortex at a certain point in the permanent magnet can be decomposed into two mutually perpendicular eddy current densities; it can be determined by
To evaluate the effect of the current densities, catalyst, and UV light on the disinfection process, samples underwent LED UV-A lamp treatments (at 360, 480, and 600 mW [cm.sup.-2]), with an electrode of thin layer ZnO nanoparticles immobilized on Zn (at 5%, 10%, and 15%), different current densities (at 3, 6, and 9 mW [cm.sup.-2]), different pHs (at 6, 7, and 8), and different radiation times (at 7.5, 15, and 30 min).
Layers with different porosities were formed by applying current densities of 5-50 mA.cm-2 in a solution of aqueous 38%wt HF and ethanol (2:3) electrolyte.
