As a new energy source with huge potential, fuel cells are efficient and clean power generation devices that can continuously input fuel from the outside and directly convert chemical energy into It can also generate electricity and continuously supply power to the outside world. It can also alleviate the energy crisis, reduce power construction, reduce environmental pollution, and is a need for power market development and national defense and other power supply guarantees. Therefore, there is a need to develop its application.
Fuel cells, known as the future automotive energy technology, have always had high hopes. This technology was once called a good choice for future automobile power, and many automobile companies are also following suit. Polytetrafluoroethylene proton membrane is also gradually becoming known to the public.
The editor will briefly talk to you about the principles of fuel cells. The fuel cell actually does not burn hydrogen, but allows the hydrogen to pass through a proton exchange membrane containing a catalyst, where the hydrogen combines with oxygen sucked in from the outside and releases electrons. Drain water vapor.
At present, proton exchange membrane fuel cells and alkaline fuel cells are most commonly used. Proton exchange membrane fuel cell (PEMFC) is a new generation of fuel cell that has developed rapidly in recent years. It has the advantages of high energy efficiency and energy density, small size and weight, fast start-up speed, guaranteed and reliable operation, and wide application. Especially It is widely used in automobiles. PEMFC is a commercial fuel cell under development.
The fuel cell proton exchange membrane is a solid electrolyte membrane, which functions to isolate fuel and oxidant and transfer protons (H + ). In practical applications, proton exchange membranes are required to have high proton conductivity and good chemical and mechanical stability.
In the field of fuel cells, polytetrafluoroethylene proton membrane can be used as the supporting base membrane of MEA proton exchange membrane, which has good The mechanical properties and high open porosity and uniform pore size ensure good performance of the fuel cell. At the same time, the thickness of the PTFE proton membrane is very thin, which allows it to obtain good operating performance by occupying only a small space.
