A seal structure of a fuel cell includes an interrupted back-up disposed at least one of a connecting gas passage and a connecting coolant passage. The back-up located on one side of a separator and a portion of a seal line located on the other side of the separator are disposed such that the back-up and the portion of the seal line are overlapped with each other in a fuel cell stacking direction. The interrupted back-up may be formed in the seal or in the separator.

A fuel cell (10) includes a lamination (11) of a plurality of unit cells (30), current collector plates (12, 12) arranged at both ends of the lamination (11), end plates 16, 16 respectively provided outside the current collector plates (12, 12) with 5 insulating plates (14, 14) interposed therebetween, and fastening members (18) for fastening the end plates (16, 16) in the laminating direction to apply desired pressing force to the lamination (11). A barcode (41) corresponding to particular information relating to a unit cell (30) is provided on the exposed side surface of a separator (38) of the unit cell (30). According to this fuel cell (10), the barcode 41 can be easily read requiring no disassembly of the fuel cell (10). Moreover, as the information relating to the fuel cell can be obtained from the barcode (41), the information that cannot be determined from outer appearance can be obtained, resulting in improved service operations.

Each of collectors 22 of an electrode structure 20, which partially constitutes a polymer electrolyte fuel cell, is formed from a metal lath MR having a large number of through-holes. A stopping portion 22a in which the through-holes are reduced in diameter is formed at a peripheral end portion of the collector 22. The peripheral end portion of the collector 22 is folded; subsequently, the folded peripheral end portion is pressed, thereby forming the stopping portion 22a. A resin seal portion 23 for sealing introduced fuel gas and oxidizer gas is formed integrally with the stopping portions 22a by insert molding which is performed such that an injected molten resin encloses the stopping portions 22a. The resin seal portion 23 formed integrally with the stopping portions 22a can reliably prevent inflow of the molten resin toward central portions of the collectors 22.

In a forming press, a blank is pressed formed into a press-formed workpiece by means of an upper die and a lower die, while a peripheral edge portion of the blank is clamped by means of a die and a blank holder insert of the forming press. Subsequently, a central portion of the press-formed workpiece is partially held by means of the upper die and the lower die so as to draw a peripheral portion of the press-formed workpiece away from the central portion thereof, thereby removing strain from the press-formed workpiece.

A banknote handling apparatus 10 comprises a casing 12, an inlet 20 configured for inserting banknotes into the casing 12 from the exterior thereof, a plurality of storages 40 provided in a lower portion of the casing 12, in a substantially horizontal direction and in parallel relative to one another, and respectively adapted for storing therein the banknotes, and an escrow storage 42 juxtaposed with the respective storages 40 in the casing and adapted for escrowing therein the banknotes inserted into the casing 12 from the exterior thereof through the inlet 20. A transport unit 30 adapted for transporting the banknotes between any two of the inlet 20, respective storages 40 and escrow storage 42 is provided above the respective storages 40 and escrow storage 42 in the casing 12. In addition, a plurality of diverters 36 are provided at diversion points 35 in the transport unit 30 toward each of the storages 40 and escrow storage 42, respectively. Each diverter 36 is adapted for diverting the banknotes transported by the transport unit 30 into a specified storage 40 or escrow storage 42.
摘要:
A fatty acid such as an acetic acid or a butyric acid is added to a fuel gas for a fuel cell as an odorant. This makes it possible to add an odor to the fuel gas without poisoning an electrode catalyst and an electrolyte, and to prevent the odor from remaining in an exhaust gas emitted from the fuel cell.

Separators for unit cells of a fuel cell each have a plurality of through holes extending therethrough and a recessed portion formed in a surface thereof. In a fuel cell incorporating such separators, the recessed portion of each separator forms an in-cell oxidative gas passage, together with an adjacent cathode. An oxidative gas, supplied from an external device into the fuel cell, is distributed from an oxidative gas supply manifold formed by holes of the separators, to the in-cell oxidative gas passages. The oxidative gas is then collected in an oxidative gas discharge manifold formed by holes of the separators, and conveyed out of the fuel cell by the discharge manifold. During the passage through each in-cell oxidative gas passage, the oxidative gas flows via an oxidative gas transit manifold formed by holes of the separators.

There is provided a banknote handling system including: a reception unit configured to receive a banknote that has been put therein; a recognition unit configured to recognize the banknote that has been received by the reception unit; a storing unit having at least one first cassette configured to store or escrow the banknote that has been recognized by the recognition unit, and at least one second cassette configured to store the banknote that has been recognized by the recognition unit; an operation unit configured to receive a deposit-confirmation instruction for the banknote that has been escrowed in the first cassette; and a control unit configured to cause the banknote that has been recognized by the recognition unit to be escrowed in the first cassette and to cause, when the deposit-confirmation instruction is received by the operation unit, the banknote that has been escrowed in the first cassette to be stored in the second cassette.
