A method of preparing a bipolar plate for a fuel cell is disclosed. The method includes (a) using an electrically conductive filler and a polymer binder to prepare a bipolar plate blank, (b) vacuum-sealing the bipolar plate blank in a metal foil bag, (c) applying hot isostatic pressing to the bipolar plate blank vacuum-sealed in the metal foil bag at a pressure greater than 100 MPa and a temperature of 150-400° C., and (d) peeling the bipolar plate blank that has undergone the hot isostatic pressing from the metal foil bag, and thereby obtaining the bipolar plate. A bipolar plate prepared by the method is also disclosed.

An apparatus for molding a pouch, the pouch having a first seating part and a second seating part, that are connected to each other, the pouch being configured such that when an electrode assembly is mounted and sealed therein, the first seating part and the second seating part are folded to cover top and bottom surfaces of the electrode assembly, and the first seating part and the second seating part are in contact with each other. The apparatus includes, a lower mold in which a first groove recessed by a predetermined depth from a top surface thereof is formed, and a second groove is additionally recessed from a bottom surface of the first grove; and an upper mold on which a flat portion is formed on one surface thereof, which is inserted into the first groove, and a protrusion inserted into the second groove protrudes from the flat portion.

Provided is a method for manufacturing a fiber reinforced plastic molded body, the method including: performing thermocompression molding, by using a molding die, on a molding precursor which is obtained by arranging a prepreg including a thermosetting resin and a fiber around a thermoplastic solid body.

Tool arrangement for compacting a composite preform assembly comprising a support structure preform and an array of component preforms each extending from the support structure preform and spaced apart along the support structure preform. The tool arrangement comprises a support tool defining a lay-up surface for laying up the support structure preform; a plurality of component moulds, each component mould comprising a pair of blocks configured to cooperate with one another to receive and compact a respective component preform extending from the support structure therebetween, each block having a compaction surface for engaging the component preform and a driving surface.

A tool for fabrication of a thermoplastic panel includes a sealed vessel, a membrane and a heater. The sealed vessel defines a volume. The sealed vessel includes first and second fluid ports. The membrane is disposed within the volume to define first and second chambers. The first chamber receives a skin and a core of the thermoplastic panel. The first chamber selectively applies a first fluidic pressure to the skin and the core in response to receiving a first fluid via the first fluid port. The membrane abuts a major surface of the thermoplastic panel. The second chamber selectively applies a second fluidic pressure to the membrane in response to receiving a second fluid via the second fluid port. The heater selectively directs heat toward the first chamber. A method for fabrication of the thermoplastic panel is provided. Various examples of thermoplastic panels are also provided.
