    摘要: A frequency synthesizer. The frequency synthesizer comprises a harmonic locked phase/frequency detector, a low pass filter, a voltage controlled oscillator, and a frequency divider. The harmonic locked phase/frequency detector receives a reference signal and a divided signal. The low pass filter is coupled to the harmonic locked phase/frequency detector. The voltage controlled oscillator is coupled to the low pass filter and provides an output signal. The frequency divider is coupled between the voltage controlled oscillator and the harmonic locked phase/frequency detector. Frequency of the divided signal is a harmonic frequency of the reference signal.

    摘要: The present invention provides a sealing structure for a bipolar plate of a fuel cell. The sealing structure includes a plurality of bipolar plates and a gas guidance and reaction layer. A gas channel is placed laterally onto the bipolar plate corresponding to the gas guidance and reaction layer. A gasket is located between a bipolar plate and the gas guidance and reaction layer. A permeable portion is formed on the gasket corresponding to the gas channel. A concave surface is placed laterally on the bipolar plate corresponding to the gas guidance and reaction layer for mating with the gasket. When the bipolar plate, gas guidance and reaction layer and gasket are fastened, the deformation amount of the gasket is accurately controlled through the height limitation of the concave surface.
