  • Patent number: 12002962
    Abstract: Disclosed is a method for manufacturing a dry electrode. The method allows determination of the micro-fibrilization degree of a binder resin from the crystallinity of the binder resin. Based on this, the processing conditions of mixed powder for electrode or an electrode film may be controlled. In this manner, it is possible to check and control the processing conditions easily and efficiently. In addition, the method for manufacturing a dry electrode includes a kneading step using a kneader under a low speed and high temperature and pulverization step. Therefore, there is no problem of blocking of a flow path caused by aggregation of the ingredients, which is favorable to mass production.

  • Publication number: 20240170687
    Abstract: A catalyst for fuel cells and a method of manufacturing the catalyst are disclosed. The catalyst forms shells in a dense structure so as to prevent elution of a transition metal and increases dispersibility through hydrophilization of the surface of the catalyst so as to be uniformly dispersed when an ink for forming a fuel cell electrode is manufactured. The catalyst may thus increase the performance and durability of a fuel cell.

  • Patent number: 11936075
    Abstract: Disclosed are a separator for fuel cells capable of minimizing the volume of a system and the use of sealants, and a stack for fuel cells, more particularly, a stack for solid oxide fuel cells, including the same. Specifically, by adding a metal sheet having a specific shape, position and size to the separator, the stress applied to the sealant can be uniformized, and thus the oxidizing agent and fuel can be separated and electrically isolated using only a piece of sealant. Therefore, the stack for fuel cells is characterized in that there is no variation in temperature, reactant concentration, power, or the like between respective unit cells, so delamination and microcracks do not occur, the volume is minimized, and the power density per unit volume is very high.

  • Publication number: 20240050219
    Abstract: Devices and methods for joining a first and second tissue in a patient are disclosed that include a base with a plurality of recurved tines oriented to a tine axis and extending from a first surface of the base. The tines provide unidirectional traction of the first tissue along the tine axis toward the first surface. The first tissue is secured to the first surface of the device at the plurality of recurved tines and the second tissue is secured to the device at a second surface opposite the first surface to join the first and second tissues.

  • Publication number: 20230113477
    Abstract: Devices and methods for joining a first and second tissue in a patient are disclosed that include a base with opposed first and second surfaces, and a plurality of recurved tines oriented to a tine axis and extending from the first surface of the base. The base defines four suture holes extending through the first and second surfaces of the base and configured to receive at least one suture passing between the first and second surfaces of the base. The plurality of recurved tines provides unidirectional traction of the first tissue along the tine axis toward the first surface to secure the device to the first tissue. The device is secured to the second tissue at the second surface with the at least one suture secured to at least one anchor secured to the second tissue.
