  • Patent number: 11411509
    Abstract: Systems and methods are provided to implement power supply units (PSUs) that are capable of operating on input power having different types of input voltage waveforms, including, but not limited to, pure sinusoidal waveforms, non-pure sinusoidal waveforms, and non-sinusoidal waveforms. Such a PSU may operate to continue supplying DC output power to a system load as long as the PSU is powered by any one of a variety of such different input power types, while at the same time also effectively monitoring for presence of input power provided to the PSU and shutting down the PSU in event of absence or termination of the input power to the PSU. Such a PSU may also automatically identify and adapt to changes between different types of input power while at the same time continuing to supply DC output power to a system load in an uninterrupted manner for as long as some type of input power is being provided to the PSU.

  • Publication number: 20220093945
    Abstract: A dehydrogenation method for hydrogen storage materials, which is executed by a fuel cell system. The fuel cell system includes a hydrogen storage material tank, a heating unit, a fuel cell, a pump, a water thermal management unit and a heat recovery unit. The described dehydrogenation method utilizes the heating unit and the heat recovery unit to provide thermal energy to the hydrogen storage material tank, so that hydrogen storage material is heated to the dehydrogenation temperature. The pump extracts hydrogen from the hydrogen storage material tank, so that the hydrogen storage material is under negative pressure (i.e. H2 absolute pressure below 1 atm), according to which the hydrogen storage material is dehydrogenated, and the dehydrogenation efficiency and the amount of hydrogen release are improved. The method n can reduce the dehydrogenation temperature of the hydrogen storage material, and reduce the thermal energy consumption for heating the hydrogen storage material.
