A solid polymer film capable of conducting protons. For example, the membrane made of polyethylene benzenesulfonic acid macromolecule is one kind, and its ability to transmit protons is provided by the protons on the sulfonic acid radical. This type of membrane must be humidified before it can conduct protons, otherwise they are insulators of protons; The higher the degree of humidification, the stronger its ability to conduct protons. Under the same degree of humidification, the higher the concentration of sulfonic acid ions, the stronger their ability to conduct protons. Separate anode and cathode to prevent direct contact between fuel and oxidizer, and conduct protons generated by anode to cathode.
