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 [...]

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. [...]

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 [...]

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 [...]
