  • Patent number: 12204163
    Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

  • Patent number: 11482717
    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.

  • Patent number: 7485387
    Abstract: The present invention provides a fuel cell module compatible with a dry cell. The fuel cell module includes an enclosure, a power generating unit, a hydrogen storage unit and positive/negative output ends. The hollow enclosure has an internal space, and is provided with some preset through-holes, allowing external oxygen to enter into the space. The power generating unit and hydrogen storage unit are mounted into the space of the enclosure. Positive and negative output ends are placed at both sides or adjacent at one side of the enclosure, thereby guiding the positive and negative charge generated by the power generating unit; since the fuel cell modules are compatible with existing conventional dry cells. These modules are widely applied to existing electrical or electronic products.

  • Publication number: 20080248366
    Abstract: The present invention is a fuel cell with a combined fuel supply unit and power generating unit. The fuel cell includes a fuel supply unit, a power generating unit, and an enclosure. The fuel supply or fuel storage unit is incorporated laterally or internally into the power generating unit, thereby shortening the fuel pipeline. The performance of the fuel cell is improved, and the space required for fuel cell is reduced for greater applicability.

  • Publication number: 20080160383
    Abstract: The present invention relates to a fuel cell module with a thermal feedback mechanism. The fuel cell module includes a hydrogen storage container, a fuel cell body and a housing. The hydrogen storage container has a tank, a valve, and hydrogen storage alloy. The fuel cell body is integrated with the hydrogen storage container, such that the electricity-generating part of the fuel cell body faces the hydrogen storage container. Furthermore, heat generated from the electrochemical reaction can be fed back to the hydrogen storage container. This heat could increase the temperature of the hydrogen storage container, leading to a more stable discharge reaction and subsequently improving the performance of the fuel cell.
