Hydrogen generating apparatus that is capable of controlling the amount of hydrogen generation. The hydrogen generating apparatus has an electrolyzer, a first electrode, a second electrode, a switch, which is located between the first electrode and the second electrode, a flow rate meter, which measures an amount of hydrogen generation in the second electrode, and a switch controller, which receives a set value, compares the amount of hydrogen generation measured by the flow rate meter with the set value, and controls an on/off status of the switch. The amount of hydrogen generation can be controlled by use of on/off time and/or on/of frequency of the switch.
摘要:
The present invention relates to novel fusarisetin compounds separated from Fusarium sp. FN080326 and having an anticancer activity, and to the use thereof. In detail, novel fusarisetin compounds separated and purified from Fusarium sp. FN080326, which is in turn separated from a soil sample, have an inhibitory activity on the proliferation and transfer of cancer cells such as breast cancer cells, liver cancer cells or myeloid leukemic cells. Therefore, the compounds can be effectively used for anticancer compositions containing the compounds as active ingredients.

A method and apparatus for allocating radio resources in a wireless communication system are provided, in which a Base Station (BS) transmits information indicating current allocated resources to a Mobile Station (MS) in every predetermined periods, defines a virtual resource space with current unallocated resources, when the MS requests resource allocation, generates resource allocation information about resources allocated in the virtual resource space, and transmits the resource allocation information to the MS.
摘要:
A hydrogen generating apparatus and a fuel cell power generation system having the hydrogen generating apparatus are disclosed. The hydrogen generating apparatus can include an electrolyte bath configured to contain an electrolyte solution, an anode placed inside the electrolyte bath and configured to generate electrons, a cathode placed inside the electrolyte bath and configured to receive the electrons from the anode to generate hydrogen, a condensation plate disposed on a transfer path of the hydrogen such that moisture carried in the hydrogen is condensed and the hydrogen is separated, and a heat exchanger configured to cool down the condensation plate heated by the moisture carried in the hydrogen. The hydrogen generating apparatus of the present invention can increase the efficiency of hydrogen generation by removing the moisture carried in the hydrogen while generating the hydrogen and reusing the moisture circulated through the electrolyte solution.
摘要:
A frame configuration method and apparatus for sending data via an RS in a broadband wireless communication system are provided. In the reception mode, the RS monitors reception of data in an (n−1)th frame from an MS and reception of data in an nth frame from a BS. The RS classifies the data received from the MS and the data received from the BS as combinable data to be sent in combination or as non-combinable data to be sent separately, and stores the classified data distinguishably. When the RS transitions to a transmission mode, it determines whether to XOR-operate or mask the stored data. If the stored data can be masked, the RS XOR-operates the stored data and sends the masked data to the BS and the MS.

An apparatus and a method for providing a handover using an Mobile Station IDentifier (MS ID) in a wireless communication system are provided. In the method, at least one Base Station (BS) ID index assigned to a serving base station by at least one neighbor base station is confirmed. A target base station for a handover is confirmed. A temporary MS ID is formed using a BS ID index assigned to the serving base station by the target base station, and an MS ID index assigned to the mobile station by the serving base station. A network re-entry procedure with the target base station is performed using the temporary MS ID. Communication with the serving base station is performed until the network re-entry procedure with the target base station is completed.
摘要:
A cell unit for a fuel cell can include an electrolyte membrane, an electrode unit that includes an anode formed on one side of the electrolyte membrane and a cathode formed on the other side of the electrolyte membrane, and a porous current collector formed by coating a conductive material onto the porous surfaces of the electrode unit. It can be possible to reduce the contact resistance between the electrodes (the anode and the cathode), and their respective current collector, to thereby increase current collection efficiency and it can also be possible to make the thickness of the end plates thinner than a conventional design without sacrificing performance, to thereby decrease the overall size of a fuel cell.
