Abstract: A method of edge coating includes preparing a stack including a plurality of articles interleaved with spacer pads. A layer of coating material is formed on a surface of a coating roller. A perimeter of the stack is positioned at a select coating gap relative to the surface of the coating roller, and the coating material is transferred from the surface of the coating roller to perimeter edges of the articles in the stack.

Abstract: The instant disclosure relates to a manufacturing method of cathode catalyst, comprising the following steps. Initially, mix an organic medium with an iron-based starting material and a nitrogen-based starting material to form a mixture. Followed by adding a carbon material to the mixture and subsequently executing a heating process to form a solid-state precursor. Then mill the solid-state precursor to form a precursory powder. Successively, calcinate the precursory powder in the presence of NH3 to form a cathode catalyst. The cathode catalyst can reduce the activation energy of hydrogen ion reacting with oxygen to make water. The instant disclosure further provides an ozone-generating device.

Abstract: A cell module includes an anode, a cathode and a proton exchange membrane. The anode adheres to one side of the proton exchange membrane while the cathode adheres to the opposite side thereof. The anode comprises a substrate and at least one diamond-like carbon layer covering the substrate. The present disclosure further provides an ozone generator and a method using the same.
