  • Patent number: 10756363
    Abstract: A hydrogen circulation system for fuel cell includes a hydrogen supply pipeline, a return pipeline, a buffer tank, an ejector, a differential pressure valve, a solenoid valve, and a controller. The return pipeline connects a hydrogen outlet of a fuel cell stack and the hydrogen supply pipeline. The buffer tank is installed at the return pipeline. The ejector is installed at the hydrogen supply pipeline for connecting the buffer tank. The differential pressure valve is between a hydrogen source and the ejector for adjusting a pressure in the hydrogen supply pipeline based on a pressure difference between an anode inlet and a cathode inlet of the fuel cell stack. The solenoid valve is installed at the return pipeline between the buffer tank and the hydrogen outlet. According to an output voltage or a load of the fuel cell stack, a switch of the solenoid valve is controlled by the controller.

  • Patent number: 10326151
    Abstract: A modular structure of a fuel cell is provided, which includes a membrane electrode assembly (MEA), at least one first electrode plate, at least one second electrode plate, at least one first fixing element and at least one second fixing element. The first electrode plate is disposed at one side of the MEA and has at least one first through hole. The second electrode plate is disposed at the other side of the MEA and has at least one second through hole corresponding to the first through hole. The first fixing element and the second fixing element correspond to each other, and are joined to each other through the first through hole and the second through hole to fix the first electrode plate and the second electrode plate for the first electrode plate, the MEA and the second electrode plate to form a single cell module.

  • Publication number: 20120125902
    Abstract: An absorbing method and apparatus for rear side laser process is disclosed. A conductive plate contacts or separates above a flexible substrate which is deposited a conductive film therebelow. A power source electrically connects the conductive plate and the conductive film, or only the conductive plate. After the power source provides voltages, a Coulomb electrostatic force is produced between the conductive plate and the conductive film, so as to absorb the flexible substrate and the conductive film. A light source is disposed above the conductive plate and emits a laser beam which in series passes through the conductive plate and the flexible substrate, and then focuses on rear side of the conductive film to process. Therefore, it is able to avoid the flexible substrate bent or drooping, and improve yield rate.
