PEMFC--Proton Exchange membrane fuel cell

PEMFC- Proton Exchange Membrane fuel cell——Proton Exchange membrane fuel cell coating——Shanghai Yangmi ultrasonic spraying

PEMFC- Proton Exchange membrane fuel cell:

• Electrolyte: water - based acid polymer membrane
  

• Also known as polymer electrolyte membrane fuel cells
  

• Both electrodes use platinum-based catalysts
  

• Hydrogen is usually used as fuel
  

• Operating at relatively low temperatures
  

• High temperature fuel cells use mineral acid electrolytes
  

PEMFC is the most commonly used automotive fuel cell. It uses a polymer membrane as an electrolyte and a carbon electrode containing platinum. The latter makes the battery relatively expensive, but it can be recycled, and platinum alternatives are being studied that may reduce costs. The cell requires only oxygen and pure hydrogen for fuel and produces only water as a residual substance. Operating at low temperatures of around 80 degrees Celsius, they can meet the vehicle's high demand for high-density power during the initial phase. Fuel cell electric vehicles (FCEVs) that use pure hydrogen to drive a motor have no emissions other than water.

In order for hydrogen to be widely adopted, expensive filling infrastructure would have to be built. Refueling is not as simple as gasoline and so on. In principle, hydrogen can be produced on site by adding electrolytic cells (devices that carry out the hydraulic electrolysis process) as well as power and water sources. This eliminates the need to liquefy the hydrogen and transport it to a filling station. However, the hydrogen produced must be compressed before it can be delivered to the vehicle, and the heat generated during compression must be removed through a cooling process. Liquefaction is not strictly necessary in transportation, but it can improve efficiency. The liquefaction process involves compression and cooling to below 240 degrees Celsius, which requires a lot of energy. All components of an aeration system require energy and equipment, making it relatively complex and expensive.

The development of fuel cell industry cannot be separated from the research and innovation of ultrasonic spraying technology.
