Gas Diffusion Layer Gas diffusion layer (GDLs) perform the significant functions in the proton exchange membrane fuel cells (PEMFCs), such as maintaining the water balance in the membrane electrode assem-bly (MEA) by allowing appropriate amount of water to move in and out from the reaction zone, providing the mechanical sup-port for the MEA and electrical contact between the electrodes and the current collectors. The key characteristics of GDLs include structural design, [...]

Air-breathing PEM Fuel Cells Newly developed portable electronics require power sup-plies with a higher energy density and longer operation time. As a substitute for currently used batteries, fuel cells are beingconsidered based on their potential to fulfil these requirements. Among the various types of fuel cells, the polymer electrolyte membrane fuel cell (PEMFC) has many advantages for portable electronics such as a low operating temperature, fast response, design flexibility, high power density [...]

GDE Hot Pressing Membrane Electrode GDE Hot Pressing Membrane Electrode – Membrane Electrode Coating The first generation of MEA preparation technology adopts the hot pressing method to press the CL-coated cathode and anode GDL on both sides of the PEM to obtain MEA. This MEA is called a “GDE” structure. The preparation process of GDE-type MEA is relatively simple. Because the catalyst is coated on GDL, it is beneficial to [...]

Ultrasonic Spray Coating Deposition Ultrasonic spray coating as deposition technique for the light-emitting layer in polymer LEDs In this work the ultrasonic spray coating technique is introduced as an alternative wet solution process for the deposition of the (Super Yellow) light-emitting layer for polymer light-emitting diodes (PLEDs). An investigation on the use of this coating technique in ambient conditions is performed and a comparison with spin coated PLEDs in inert [...]

Ultrasonic Spray Pyrolysis For Nanoparticles Synthesis Ultrasonic spray pyrolysis for nanoparticles synthesis. This article presents new findings regarding the effects of precursor drop size and precursor concentration on product particle size and morphology in ultrasonic spray pyrolysis. Large precursor drops (diameter > 30 μm) generated by ultrasonic atomization at 120 kHz yielded particles with holes due to high solvent evaporation rate, as predicted by the conventional one particle per drop [...]

Ultrasonic Mist Nozzle Ultrasonic mist nozzle operates by converting high frequency sound waves into mechanical energy that is transferred into a liquid, creating standing waves. As the liquid exits the atomizing surface of the nozzle, it is broken into a fine mist of uniform micron sized droplets. Unlike pressure nozzles, ultrasonic nozzles do not force liquids through a small orifice using high pressure in order to produce a spray. Liquid [...]
