Cheersonic has focused on the automation and ultrasonic coating technology for more than two decades and supplies the ultrasonic thin film coater in the [...]

Spray Coating of AEMFC Spray Coating of AEMFC - Fuel Cell Coating - Cheersonic In the case of PEMFCs, high-power density was secured and research and development for commercialization have made significant progress. However, there are technical limitations and high-cost issues for the use of precious metal catalysts including Pt, the durability of catalysts, bipolar plates, and membranes, and the use of hydrogen to ensure system stability. On [...]

Ultrasonic Pyrolysis Solution Ultrasonic Pyrolysis Solution - Ultrasonic Coating - Cheersonic Cheersonic focused on the ultrasonic coating technology more than 20 years. Uniform thin film Indium Tin Oxide (ITO), Aluminum Doped Zinc Oxide (AZO), Zinc Oxide (ZnO), and Fluorine Doped Oxide layers are often created using an ultrasonic spray pyrolysis technique. The ultrasonic spray pyrolysis machine UAM2000 produces highly uniform size of droplets that achieve the optimal size [...]

The Catalyst Layer of Pem Fuel Cell Fuel cells enable a clean and efficient production of heat and power from a diversity of primary energy sources. Even though,substantial improvements have been made over the past few years in the cell design and material utilization, several technical barriers still exist that prevent the PEM fuel cells from commercialization.Among the various obstacles, the most important are low cell performance due [...]

Spray Coating of SOFCs Spray Coating of SOFCs - Fuel Cell Catalyst Coating Systems - Cheersonic Although solid oxide fuel cells (SOFCs) are part of the prospective energy infrastructure, some challenges in their adaption still remain. Besides the need for lower operating temperatures, fuels that are easier to store, cheaper, and/or more abundant than hydrogen are preferred. While external reformers enable the transformation of various compounds into hydrogen [...]

Ultrasonic Coater Could Produce Uniform Thin Coatings Cheersonic's ultrasonic coater could produce highly durable and uniform thin coatings for catalyst coated membrane (CCM), gas diffusion electrode (GDE), polymer membrane, micro porous layer (MPL). Cheersonic's fuel cell catalyst coating systems are uniquely suited for these challenging applications by creating highly uniform, repeatable, and durable coatings. From R&D to industrial scale production, our non-clogging technology results in greater control of [...]

Spray on MEA The membrane electrode assembly provides sites for chemical reactions occurring inside a fuel cell to convert the fuel into usable electrical power. The assembly includes a gas diffusion layer, 5-layer membrane, and 3-layer membranes, gaskets, or sealing components. These components are fabricated individually and then pressed together at high temperatures and pressures and are in the form of stacks. The performance and stability of fuel [...]

Types of Fuel Cells A fuel cell (actually a group of cells) has essentially the same kinds of components as a battery. As in the latter, each cell of a fuel cell system has a matching pair of electrodes. These are the anode, which supplies electrons, and the cathode, which absorbs electrons. Both electrodes must be immersed in and separated by an electrolyte, which may be a liquid [...]
