Due to the global energy crisis and the increasing environmental pollution caused by traditional energy sources, fuel cells, as a new type of high energy density, high energy conversion rate, and reliability The power supply device has received widespread attention. ptfe proton exchange membrane has also gradually entered the public eye.
There are many types of fuel cells. Currently, fuel cells are mainly divided into six categories: Alkaline Fuel Cell(AFC) , Phosphate fuel cell (PAFC), Molten carbonate fuel cell (MCFC), Solid oxide fuel cell (SOFC) em>, proton exchange membrane fuel cell (PEMFC) and direct methanol fuel cell (DMFC). Compared with other types of fuel cells, PEMFC, which uses a polymer proton exchange membrane as the electrolyte, has the advantages of low operating temperature, fast start-up speed, modular installation and convenient operation. It is considered to be the ideal choice for electric vehicles, submarines, various A good alternative power source for portable power supplies, power grids and stationary power supplies.
Generally speaking, a proton exchange membrane fuel cell consists of a porous electrode coated with a catalyst and a porous electrode placed between the two Composed of proton exchange membrane (PEM). Obviously, the proton exchange membrane is one of the core components of PEMFC. In fact, this fuel cell is named after the proton exchange membrane.
As the electrolyte of the battery, the functions of PEM include:
1. Prevent the cathode and anode of the battery from contacting, avoid the direct reaction of the two-pole fuel, and ensure energy utilization;
2. Transmit hydrogen protons. PEM with high proton conductivity is the guarantee of battery efficiency;
3. Block electrons to ensure that electrons are transmitted from the external circuit to achieve the purpose of using electrical energy. Therefore, PEM is essentially a dense selectively permeable membrane.
The currently independently developed ptfe proton exchange membrane is the supporting base membrane of the MEA proton exchange membrane. It has good mechanical strength and uniformity. The pore diameter and opening ratio ensure good performance of the fuel cell and play a key role in the overall performance and service life of the hydrogen fuel cell.
ptfe proton exchange membrane technology has always been the core of business, in biopharmaceuticals, equipment, food and beverages, semiconductor processes, communications It plays an indispensable role in many fields, with pore-forming capabilities ranging from 0.1μm to 1μm, providing functional solutions such as fine filtration, bacteria and virus removal, waterproofing, breathability, and sound transmission.
