MEA Fabricated by Ultrasonic Spray

MEA Fabricated by Ultrasonic Spray Due to the high-quality power, scalability, and fast start-up, proton exchange membrane fuel cells (PEMFCs) are a promising future power source. Membrane electrode assemblies (MEAs) play an important role in performance. A MEA is a composite of a GDL, catalyst layer (CL), and proton exchange membrane (PEM). The electrochemical reaction occurs at the CL. The electrochemical reaction needs a three-phase boundary (TPB) where [...]

Classification of Balloons

Classification of Balloons The performance of the balloon is largely determined by its material, so the classification of the balloon is also the classification of the balloon material. At present, there is no universal criterion for the classification of balloons. There are two types of balloon classification methods recognized by most people in the industry: 1) Balloons are classified into high pressure balloons and low pressure balloons according [...]

Catalyst Coated Membrane Technique

Catalyst Coated Membrane Technique Useing of an ultrasonic spray for the fabrication ultra-low Pt loading MEAs with the catalyst coated membrane technique. Cathode Pt loading coated with catalyst ink by the ultrasonic spray method was investigated. It was determined that 0.272 mgPt/cm2 showed the best performance for 33 wt% Nafion content in a catalyst coated membrane when it was ultrasonically spray coated with SGL 24BC gas diffusion layer. [...]

Development of Balloon Materials

Development of Balloon Materials Development of Balloon Materials - Catheter Coatings - Cheersonic So far, the vast majority of medical balloons are made of polymer materials. The original medical balloons were made of soft polyvinyl chloride (PVC). Compared with today's balloons, this kind of balloon has a thicker wall but low pressure resistance. As scientists continue to screen and explore polymer materials, in the early to mid-1980s, balloons [...]

Ultrasonic Spray For MEA Fabrication

Ultrasonic Spray For MEA Fabrication Ultrasonic spray coating technique is replacing air spray coating technique in a wide range of industrial and R&D applications, such as photo resistor coating, solar cell industry and fuel cell industry. Ultrasonic spray coating is a technology that is more precise, more controllable, and tighter of drop distribution. Tight drop distribution and non-clogging ultrasonic create very uniform thin films, therefore, ultrasonic spray coating [...]

Balloon Catheter

Balloon Catheter Balloon Catheter - Balloon Catheter Coating Systems - CHEERSONIC In 1977, Swedish doctor Gruentzing successfully performed the first percutaneous transluminal coronary angioplasty (PTCA), marking the beginning of interventional medicine. As a young and energetic professional technique, interventional therapy has attracted more and more people's attention for its advantages of small trauma, safety, and reliability. In the past 30 years, especially in the past 10 years, interventional [...]

The basic difference between PEMFC and SOFC

The basic difference between PEMFC and SOFC PEMFC hydrogen is the fuel, which requires high purity. The electrolyte is a high-molecular polymer, usually a proton conductor. Catalyst platinum carbon, gas diffusion layer carbon. Bipolar plates have carbon and metal. The working temperature is low. The electrode reaction zone involves a three-phase reaction, which is more complicated. Consider water management issues. SOFC can use hydrocarbons as fuel. The electrolyte [...]

Shielding Spray

Shielding Spray Shielding Spray - Ultrasonic Atomizer Nozzles - Cheersonic Dispersion of shielding coating: In order to improve the dispersion effect of graphene, an ultrasonic intelligent disperser is selected. First, an ultrasonic intelligent disperser is used to pre-disperse graphene to reduce the high surface energy of graphene, use electrostatic repulsion and steric hindrance to avoid agglomeration of rabbit graphene, and further improve the dispersibility of graphene. Ultrasonic coating [...]
