Abstract: A fuel cell energy circulative utilization system includes an input energy, a first electric cell having an electricity output terminal and an energy output terminal, a second electric cell having an electricity input terminal, an energy input terminal, and an energy output terminal, and an energy circulation control device connected among the first and second electric cells and the input energy. The input energy includes an energy source containing hydrocarbons or hydrogen and connected to an energy input port of the first electric cell in order to make the first electric cell outputs electricity through the electricity output terminal and energy products of thermal energy and water through the energy output terminal.

Abstract: An electric vehicle parking energy supply system includes at least one electric power control unit that is connected with at least one electric power generation system, a parking tower having multiple vehicle carrying platforms that are movable in multiple axes for receiving electric vehicles to park thereon, multiple power buses, a power charging control unit arranged on each vehicle carrying platform for connection with and charging the electric vehicle, and at least one electric vehicle charging management center. The power charging control unit controls bidirectional electric energy supply for supplying working power required by the parking tower, the vehicle carrying platforms, and the power buses and selling extra power back to a commercial power supply. The power buses are arranged longitudinally to each correspond to one side of a predetermined location of each of the vehicle carrying platforms of the parking tower.

Abstract: A liquefied natural gas transportation/distribution and vaporization management system includes a transportation/distribution platform, on which at least one gas transportation/distribution section, a vaporization treatment section, and a central management section are arranged. The gas transportation/distribution section allows at least one liquefied natural gas train to unload liquefied natural gas. The vaporization treatment section is connected to the gas transportation/distribution section. The vaporization treatment section includes therein at least one fuel cell module, so that heat exchange may be conducted with byproduct of thermal energy and water generated in a power generation operation of the fuel cell module to vaporize liquefied natural gas from the gas transportation/distribution section and to feed the vaporized natural gas into a local area gas supply pipeline or a temporary gas storage section for storage and for feeding to the fuel cell module of the vaporization treatment section.

Abstract: An intelligent electric grid management system and method includes at least one feeder line controller, which is arranged between a secondary power transforming station and at least one power supply feeder line to receive high voltage power and a control instruction from the secondary power transforming station and to store and set, in advance, digital code data of each power supply feeder line, a smart meter of a user end, appliance loads, and priority cutoff levels, a plurality of smart meters, which are each connected between the distribution line of each user end and at least one power feeder line, wherein the smart meter and the feeder line controller transmit therebetween a user end load ON/OFF control signal and a load state detection feedback signal through the power supply feeder line by means of the power line communication protocol; and a plurality of intelligent load receptacles, which are connected to the receptacle power line of the distribution line of the user end and the household appliance l

Abstract: An autonomously controlled greenhouse cultivation system includes a fuel cell module, an environment detection and control module, and environment set-up devices. The fuel cell module includes input terminals and output terminals. After fuel and air are received through the input terminals, the output terminals supply, respectively, various environmental products, including electrical power, thermal energy, carbon dioxide, and water, which are fed to the environment detection and control module that controls the output of these environmental products and includes detection units and control units to detect and effect feedback control of illumination, temperature, humidity, carbon dioxide concentration, and water level.
