  • Patent number: 10494727
    Abstract: A control system for an electrolytic cell includes a voltage converter converting an input voltage into a decomposition voltage, a temperature sensor generating a sensed temperature, an electric power sensor generating a sensed voltage, and a control unit storing voltage-temperature characteristics. The control unit determines a voltage that corresponds to the sensed temperature according to one of the voltage-temperature characteristics, and generates, according to a difference between the voltage thus determined and the sensed voltage, a control signal which is provided to the voltage converter such that the decomposition voltage decreases along with increase in the sensed temperature.

  • Patent number: 9976221
    Abstract: An electrolytic tank apparatus includes a tank body and at least one electrode set. The tank body defines an outer tank space for receiving a coolant, and at least one inner tank space that is surrounded by the outer tank space and that is not in fluid communication with the outer tank space. The tank body has a tank wall formed with a coolant inlet and a coolant outlet each communicating with the outer tank space. The electrode set is disposed in the inner tank space and includes at least one cathode plate, at least one anode plate, a cathode-connecting structure that is electrically coupled to the cathode plate, and an anode-connecting structure that is electrically coupled to the anode plate.

  • Patent number: 5017166
    Abstract: A power-driven surfboard, whch comprises a DC power supply connected between a motor and a pressure-controlled power switch, which is controlled by a pressure board mounted on the top face thereof to drive the motor to operate, and a propeller connected to the motor through a transmission shaft. Once the pressure board is stepped on, the DC power supply is connected to provide the motor with necessary working voltage so as to drive the propeller to propel the surfboard to move forward on water surface.
