  • Publication number: 20230226644
    Abstract: The present invention discloses a laser scribing device that produces optimal scribing lines within a target substrate based on its thickness. This is accomplished by generating multiple or an optimum number of focal points, and dynamically adjusting the focal lengths of the focal points to create optimal distances between the scribing lines. The resulting scribing lines are efficient in breaking the target substrate. The position of the focal points and the distance between them are determined based on the thickness of the target substrate, and the distance between focal points or scribing lines can be dynamically adjusted by modifying the focal lengths of the focal points.

  • Patent number: 11646431
    Abstract: A humidifier for a fuel cell is provided and includes a housing having, at a first side, a moist air supply port through which moist air is supplied from a fuel cell stack and having, at a second side, a moist air discharge port. A humidifying membrane is disposed in the housing and allows dry air to flow along the inside of the humidifying membrane. A bypass flow path is formed in the housing to allow a part of the moist air supplied to the moist air supply port to continuously flow to the moist air discharge port without passing through the humidifying membrane, thereby adjusting the amount of humidification and a differential pressure of the humidifier based on an operating condition of a fuel cell.
