The Teflon proton exchange membrane is located in the center of the membrane electrode and is the core component of the proton exchange membrane fuel cell. It plays the role of separating fuel and oxidant, conducting protons and insulating electrons. Its performance and life span directly determine the performance of the battery. and longevity.
The role of perfluorinated proton membranes in fuel cells.
Lead-acid batteries also have membranes, in which a sulfuric acid liquid membrane plays a role. Lithium batteries also have separators. Biaxially stretched membranes such as PE and PP also become conductive ions after being soaked with electrolyte. membrane, so all batteries need an intermediate membrane, and fuel cells need this membrane even more.
The hydrogen fuel cell we use now is named after the membrane, proton membrane fuel cell, which reflects the important role of this membrane in the fuel cell.
Teflon proton exchange membrane is a composite membrane using perfluorosulfonic acid material and polytetrafluoroethylene (PTFE). PTFE is the microporous medium that plays a strengthening role, while the perfluorosulfonic acid material is in the micropores. Form proton transfer channel.
This composite membrane can improve the mechanical strength and stability of the membrane, and the membrane can be made very thin, reducing the amount of perfluorosulfonic acid material, lowering the cost of the membrane, and improving the proton conductivity of the membrane.
