Ultrasonic Spraying of Membrane Materials Ultrasonic Spraying of Membrane Materials - Cheersonic The most widely used class of membrane materials today for the PEMFC are of the perfluorinated sulfonic acid (PFSA) type. However, they have the disadvantage of being inherently expensive due to the complex fluorine chemistry involved in their fabrication and too expensive to extent their application. Indeed, the Nafion based membrane shows complete domination in mechanical, [...]

Ultrasonic Spraying of GDL Ultrasonic Spraying of GDL - Ultrasonic Coating - Cheersonic The gas diffusion layers (GDL) are a fibrous porous medium that has two main functions: to ensure a uniform distribution of reactive gases on the surface of the electrodes, and the transport of electrons to or from the external electrical circuit. Gas diffusion layer (GDL) is a crucial component which is mainly responsible for the [...]

Membrane Electrode Preparation Methods Membrane Electrode Preparation Methods - Ultrasonic Coating - Cheersonic Membrane electrode assemblies (MEAs) are the core components of a proton exchange membrane fuel cell and consist of three key materials: the proton exchange membrane, the catalyst, the gas diffusion layer and the frame. The commonly referred to membrane electrode assembly is a seven-layer membrane electrode, including the proton exchange membrane, the anode catalyst layer [...]

Ultrasonic Spraying of Molten Carbonate Fuel Cells Ultrasonic Spraying of Molten Carbonate Fuel Cells - Cheersonic The molten carbonate fuel cell (MCFC) systems represent one of the most flexible systems for in-situ and stationary electrical power plants, because of their high electrical efficiency and possibility to supply hydrogen produced by different raw fuels.
