The adhesive layer 14 is formed of a cured product of an adhesive composition containing a polyurethane resin having a reactive functional group and a cross-linking agent, where the adhesive layer 14 has a gel fraction of 60 mass % or higher, a storage elastic modulus at 100° C. (G′100) of 5.0×104 Pa or higher and 1.0×108 Pa or lower, and a decreasing rate of a storage elastic modulus at 120° C. (G′120) to the storage elastic modulus at 100° C. (G′100) of 0.5 or less.

摘要: Provided are a friction stir welding (FSW) device, FSW system, and FSW method with which it is possible to expand the applications of FSW while increasing processing accuracy. In a FSW device, when a first member to be welded and a second member to be welded are continuously welded by moving a processing tool in a linear or curved manner with the processing tool, while rotating, being pressed in the axial direction against the first member to be welded and the second member to be welded, a control device executes a reaction force correction control that controls the output of support member actuators so as to cancel the reaction force acting upon the processing tool as a result of the rotation of the processing tool.

摘要: A power generation cell includes a resin-framed electrolyte membrane electrode assembly. The cathode of the resin-framed membrane electrode assembly has a larger surface dimension than the anode. An outer peripheral portion of the anode is positioned between a first buffer and a fuel gas flow field. An outer peripheral portion of the cathode is positioned between the resin frame member and the second buffer.

摘要: A fuel cell includes a membrane electrode assembly, a separator, a fluid channel, a fluid manifold, a plurality of protruding elastic members, and a plurality of sealing members. A fluid is to flow in a stacking direction through the fluid manifold. A connection channel is provided between the plurality of protruding elastic members to connect the fluid channel and the fluid manifold. The plurality of sealing members are provided adjacent to the plurality of protruding elastic members in the stacking direction and extend in a direction to cross a flow direction in which the fluid flows along the connection channel. Each of the plurality of protruding elastic members has overlapping regions that overlap the plurality of sealing members as seen from the stacking direction. The overlapping regions are separated from each other in the flow direction.

摘要: A method of selecting a thermoplastic-resin adhesive provided so as to be exposed to a fluid flow path of a power generation cell includes a load application step, an exposing step, a measurement step, and a selecting step. In the load application step, a compressive load is applied to a laminate body in a laminating direction thereof, the laminate body being formed by sandwiching an adhesive between a first resin film and a second resin film. In the exposing step, the laminate body is exposed to an environment heated to a predetermined temperature and humidified to a predetermined humidity. In the measurement step, a flow amount of the adhesive during the exposing step is measured. In the selecting step, the adhesive having the flow amount equal to or less than a predetermined amount is selected as an adhesive used for the power generation cell.
