Abstract: A power auxiliary device includes a rotor having a pivot which is connected with a power device. The rotor has multiple slots and each slot receives a certain amount of liquid therein and the liquid freely flows in the slot. When the rotor rotates, the liquid flows in the slots and generates inertia and torque differences to assist the rotor to rotate.

Abstract: The present invention discloses a hydrogen-recyclable fuel cell comprising anode set, cathode set, catalytic layer, proton exchange membrane, hydrogen delivering device, hydrogen-storage complex metal layer and hydrogen drawing device. The hydrogen delivering device delivers hydrogen to the catalytic layer which ionizes hydrogen into electrons and hydrogen ions. After the hydrogen ions pass through the proton exchange membrane, they react with the hydrogen-storage complex metal layer and the electrons to produce complex metal hydrides. The hydrogen drawing device draws hydrogen from the complex metal hydrides into the storage tank for further reuse.

Abstract: A lithium battery includes a casing having at least one reacting trough in which at least one electrode device is installed and the at least one electrode device includes a first electrode having a lithium compound that contains ionizable lithium ions and a first electric conductor. A second electrode includes at least including a layer material containing carbon or metal alloys, and a second electric conductor. A third electrode is disposed between the first electrode and the second electrode. The third electrode has an electrically conductive carrier for electroplating lithium ions and the carrier has a penetrating hole for passing lithium ions through the penetrating hole. At least one isolating membrane separates the first, second and third electrodes. The isolating membrane including a small hole for passing ions through the small holes. A control device controls the switch of a charging or a discharging status of the first, second and third electrodes.
