Problems solved by technology

Inside the fuel cell, the proton exchange membrane provides a channel for the migration and transport of protons, so that the protons pass through the membrane from the anode to the cathode, and form a circuit with the electron transfer of the external circuit to provide current to the outside world. Therefore, the performance of the proton exchange membrane has a great influence on the performance of the fuel cell Performance plays a very important role, and its quality directly affects the service life of the battery; at present, there are a large number of products that reinforce the proton membrane with inorganic materials, but due to the poor dispersion of inorganic materials, the quality of the finished membrane is low
