Title: Split Mold For Die Forging
Inventor: HAHN HOWARD SUNG
IPC: B21K1/46
Filed: 2021-03-30
Abstract: The present invention relates to a split mold for die forging. The split mold for die forging includes a plurality of split mold parts (100), a support body (200) supporting the split mold parts from the outside and a cylindrical housing (300) supporting the support body (200) from the outside, wherein the split mold parts (100) have upper and lower surfaces formed into horizontal surfaces, and have lateral surfaces formed into inclined surfaces (110, 120) having upper and lower parts tapered to both upper and lower sides, and a ring-shaped vertical surface (130) connected to the inclined surfaces (110, 120) in the upper and lower parts to have a hexahedral contour shape when viewed from a side. Due to an impact force, which is caused by the formation of a guide rod head as a head part is expanded when a puncher (600) equipped with an upper mold descends and strikes the head part, the upper and lower tapered inclined surfaces (110, 120) of the split mold parts are supported by an upper surface (210) and a lower surface (220) of the support body (200), which are tapered, thereby minimizing the displacement of the split mold parts (100) to the lower side and to the outside in a radial direction, which can lead to an effect of improving the size stability of a forged guide rod.

Title: An all-solid type battery and a method for manufacturing the same
Inventor: KIM JI YOUNG
IPC: H01M10/0562
Filed: 2021-04-06
Abstract: The present invention relates to an all-solid-state battery, provided with a solid electrolyte membrane protection member for compensating for the area difference between an electrode and a solid electrolyte membrane on a surface of the electrode so that a distal end of the solid electrolyte membrane is supported by the solid electrolyte membrane protection member. Accordingly, the distal end of the solid electrolyte membrane may be supported by the solid electrolyte membrane protective member even if the solid electrolyte membrane has low mechanical strength or high flexibility due to the inclusion of a polymer-based solid electrolyte, and thus has low shape stability. As a result, damage to the distal end of the solid electrolyte membrane can be prevented. Also, the present invention relates to a method for manufacturing the all-solid-state battery. According to the method, the solid electrolyte membrane protection member can be disposed in the area difference between the electrode and the solid electrolyte membrane in a simple way, which is very effective in terms of process convenience.

Abstract: The present invention relates to a nafion-based composite membrane for a proton exchange membrane, a method for fabricating the same, a proton exchange membrane including the composite membrane, and a fuel cell and water electrolyzer comprising the proton exchange membrane. More specifically, two types of polymers in a nafion membrane are cross-linked through esterification to form a semi-interpenetrating polymer network structure so as to prevent water mobility interference, caused by the reduction in the number of nanochannels of the existing nafion membrane and the separation of ion clusters, thereby effectively suppressing the generation of hydrogen crossover and remarkably improving proton ionic conductivity, dimensional stability, and water retention. In addition, according to the present invention, low-cost polymers are simply cross-linked to a nafion membrane to form a complex membrane having a semi-interpenetrating polymer network structure such that manufacturing costs can be significantly reduced.
