  • Patent number: 11962050
    Abstract: A method for producing a resin frame equipped membrane electrode assembly includes: a first conveyance step of supporting a sheet-shaped member having a cathode and an electrolyte membrane by a resin frame member to which the sheet-shaped member is joined and linearly conveying the supported sheet-shaped member to a pressure bonding device; a second conveyance step of conveying an anode to the pressure bonding device by way of a rotary table; and a pressure bonding step of heating and pressing the cathode and the anode from above and below by the pressure bonding device to thereby integrate the cathode and the anode together.

  • Patent number: 11876271
    Abstract: In a preparation process of a method for manufacturing a power generating cell stack, a stacking table provided with a vibratable stack guide portion projecting upward and a stack unit provided with a positioning portion guided by the stack guide portion are prepared. In the placing step, the stack unit is stacked on the stacking table by dropping the stack unit toward the stacking table while the positioning portion is stacked along the stack guide portion which is vibrated in the vertical direction.

  • Patent number: 11626598
    Abstract: A fuel cell stack includes a first metal separator and a second metal separator sandwiching a membrane electrode assembly. Bead seals are provided on the first and second metal separators. The bead seals protrude toward the membrane electrode assembly. A seal member is provided on a top part of each of the bead seals. In the process of producing the fuel cell stack, pressure medium is supplied to a coolant flow field formed between the first metal separator and the second metal separator. The supply pressure of the pressure medium is set to not less than the supply pressure of a coolant supplied to the coolant flow field during normal operation of the fuel cell stack.

  • Publication number: 20210267900
    Abstract: The present invention relates to a pre-processing method for the purpose of formulating a drug substance having non-uniform particle sizes by a manufacturing method having excellent manufacture performance. According to the pre-processing method of the present invention, additives including at least a dispersant are blended in a drug substance having a specific particle size distribution and then the resultant mixture is deagglomerated/sized to disperse and make adhere the additives onto the surfaces of the particles of the drug substance, thereby yielding a powder having a specified particle size distribution. In this manner, a pharmaceutical preparation can be manufactured with excellent manufacture performance, manufacture efficiency, and manufacture cost by a direct compression method, a wet continuous granulation system or the like. Therefore, the pre-processing method is very useful.

  • Publication number: 20180170702
    Abstract: A sheet material conveying device unwinds from a roll body a sheet-shaped member constituting a membrane electrode assembly and conveys the sheet-shaped member. The sheet material conveying device is equipped with a suction member that moves the sheet-shaped member, and a negative pressure supply unit that supplies a negative pressure to the suction member. The suction member is constituted by a porous body capable of sucking under the negative pressure one surface of the sheet material having been unwound from the roll body and is movable in a conveying direction.
