    摘要: A fuel cell system includes at least one electricity generating unit for generating electric energy through an electrochemical reaction between oxygen and hydrogen, a reformer for reforming fuel to generate hydrogen gas to be supplied to the electricity generating unit, a fuel supply apparatus for absorbing a liquid fuel stored in a fuel reservoir and supplying the fuel to the reformer and an oxygen supply source for supplying oxygen to the electricity generating unit. The fuel supply apparatus employs an absorber with capillary channels in which osmotic pressure is produced due to a concentration differential caused by thermal energy. The osmotic pressure allows the fuel to flow.

    摘要: An analog-to-digital converter includes a comparison signal generation unit and a control unit. The comparison signal generation unit determines a logic level of a comparison signal by comparing an input signal with a selected reference signal based on a switch control signal in a first comparison mode, and by comparing a difference voltage with a ramp signal based on the switch control signal in a second comparison mode. The difference voltage is generated based on the input signal and the selected reference signal such that a level of the difference voltage is lower than a fine voltage level corresponding to a voltage level of the selected reference signal in the second comparison mode. The control unit generates the switch control signal based on the comparison signal and a mode selection signal.
