Proton exchange membrane fuel cells have very high requirements for the proton exchange membrane. The proton exchange membrane must have good chemical stability, low gas permeability and many other properties. The polytetrafluoroethylene proton membrane can meet the above requirements. Require.
Fuel Cell (FuelCell) is a power generation device that directly converts chemical energy present in fuel and oxidant into electrical energy.
The basic structure of the proton exchange membrane fuel cell (PEMFC) stack discussed in this article mainly consists of a proton exchange membrane, catalyst layer, diffusion layer, and bipolar plate.
The polymer electrolyte membrane is covered with a carbon-based catalyst, which is in direct contact with both the diffusion layer and the electrolyte to achieve an optimal interaction surface.
The catalyst forms the electrode, directly above it is the diffusion layer.
The combination of electrolyte, catalyst layer and gas diffusion layer is called a diaphragm-electrode assembly.
Inside the fuel cell, the polytetrafluoroethylene proton membrane provides a channel for the migration and transportation of protons, allowing the protons to pass through the membrane from the anode to the cathode, forming a loop with the electron transfer of the external circuit, and providing current to the outside world. Therefore, the proton exchange membrane The performance of the fuel cell plays a very important role, and its quality directly affects the service life of the battery.
