GDLs of PEMFC GDLs of PEMFC - Ultrasonic Coating Systems for Fuel Cell Catalyst Coatings - Cheersonic Gas diffusion layers (GDLs), are important sub-components in PEMFC membrane electrode assemblies. The GDL, with its porous nature, plays an essential role in assisting the hydrogen oxidation and oxygen reduction reactions in the catalyst layers (anode and cathode) by allowing the reactants (hydrogen and oxygen/air) to diffuse from the flow field [...]
Wafer Thin Film Deposition Wafer Thin Film Deposition - Photoresist Coating - Cheersonic To create the tiny devices inside the chip, we need to continuously deposit layers of thin films and etch away the excess, as well as add materials to separate the different devices. Each transistor or memory cell is built step-by-step through the above process. By "thin film" we mean here a "film" that is less [...]
Effect of Gas Diffusion Layers of PEM Fuel Cells Effect of Gas Diffusion Layers of PEM Fuel Cells - Fuel Cell Coating - Cheersonic The efficiency and performance of proton exchange membrane fuel cells (PEMFCs) depends heavily on the heat and associated water imbalances because of their low operating temperature, which is typically less than 100℃. One of the parameters that directly affects both heat and water management [...]
Medical Tubing Materials Medical Tubing Materials - Tube Coating - Cheersonic Depending on the application, medical hoses and tubing can be produced from a variety of materials, including plastics such as fluorinated ethylene propylene (FEP), nylon, PVC, polyetheretherketone (PEEK), polytetrafluoroethylene (PTFE); thermoplastics Elastomers (TPE); and elastomers, especially silicone. Silica gel. Silicone is a key tubing material for medical devices, especially for implants. The unique properties of high-consistency silicone [...]
Wafer Etching Wafer Etching - Polyimide Coatings - Photoresist Coating - Cheersonic After the photolithography of the circuit pattern on the wafer is completed, an etching process is used to remove any excess oxide film and leave only the semiconductor circuit pattern. To do this requires the use of liquid, gas or plasma to remove selected excess. There are two main methods of etching, depending on the substance [...]
SOFCs Spray Coatings SOFCs Spray Coatings - Ultrasonic Spray Coating System - Cheersonic Fuel cell technologies have become, in recent years, an important subject of research and innovation. Among different types of fuel cells, the solid oxide fuel cells(SOFCs) have attracted significant attention due to high efficiency,fuel flexibility and silent operation. SOFCs are solid-state devices that utilize electrochemical reactions to generate electricity. Fuel is supplied to the anode [...]
Design Points of Handheld Medical Devices Design Points of Handheld Medical Devices - Medical Device Coatings - Cheersonic Compared with general medical devices, handheld medical devices have a wide range of functions, such as meeting patient requirements, occupying less space, convenient maintenance, and easy portability. Due to the widespread application of hand-held medical devices and great help to medical personnel and patients, many hand-held medical devices have begun [...]
Wafer Lithography Wafer Lithography - Polyimide Coatings - Photoresist Coating - Cheersonic Lithography is the "printing" of a circuit pattern onto a wafer by light, which we can understand as drawing the plan on the surface of the wafer required for semiconductor fabrication. The higher the fineness of the circuit pattern, the higher the integration of the finished chip, which must be achieved through advanced lithography technology. Specifically, [...]
Ultrasonic Coating Of SOFC Ultrasonic Coating Of SOFC - Programmable Ultrasonic Research System - Cheersonic Solid oxide fuel cell (SOFC) technology has achieved a very high level of technical refinement over more than 50 years of development. The cost of today’s state-of-the-art SOFC technology remains much too high to compete with entrenched power generation technologies. However, its high efficiency can bring additional environmental and economic benefits and minimise [...]
Artificial Blood Vessel Barrier Artificial Blood Vessel Barrier - Medical Device Coatings - Cheersonic According to industry insiders, the manufacture of artificial blood vessels involves dozens of procedures, and both textile technology and collagen coating have technical barriers that are difficult to break through. 1. The structure of blood vessels Human arteries are composed of three layers of intima, media and adventitia. Blood vessels of different diameters and [...]
