Abstract: A manufacturing method of a proton battery and a proton battery module are provided. The manufacturing method of the proton battery includes the steps of providing a positive electrode, a negative electrode, and a polymer exchange membrane, and assembling the positive electrode, the negative electrode, and the polymer exchange membrane, in which the polymer exchange membrane is interposed between the positive electrode and the negative electrode. The step of providing the negative electrode at least includes forming a carbon layer on a substrate, and performing a polarization process on the carbon layer.
