Abstract: A fuel cell stack comprises a stacked body, an end plate and a case configured such that the stacked body is placed therein. The end plate is arranged to cover an end face of the stacked body in a stacking direction and an end face of the case in the stacking direction and is fastened to the end face of the case. A placement groove is formed in at least one surface out of two surfaces of the end plate and the case opposed to each other, such that a seal member is placed in the placement groove. The end plate includes a resin layer formed to continuously cover an inner circumferential wall surface of the fluid flow path hole, a surface of the end plate opposed to the stacked body, and an outer circumferential side end of the placement groove.

Abstract: A resistance connecting device includes a case inside of which a chamber is formed. The chamber includes inside an activating unit, a gas generating unit, a first connecting portion, and a second connecting portion. The first connecting portion and the second connecting portion extend from the inside to the outside of the case in a mutually separated state and are exposed in the chamber. The activating unit is held at a first position that does not cause contact with either of the connecting portions when the gas generating unit has not been activated and moves up to a second position to cause contact with both of the connecting portions as a result of activation of the gas generating unit. The activating unit, at the second position, functions as a resistor having a predetermined electrical resistance, and connects the connecting portions to one another.

Abstract: A fuel cell stack 100 includes a fuel cell stack 10, and an end plate 30 placed at an end of the fuel cell stack 10. The end plate 30 includes a metallic plate-like body 32, and a resin layer 60 formed on a surface 32b of the plate-like body 32. The plate-like body 32 includes flow holes 39 for a reactant gas and a cooling medium, and a stripe-shaped protrusion 38 protruding from the surface 32b and which divides the surface 32b into an inner area containing the flow holes 39 and an outer area outside the inner area. The protrusion 38 includes a vertical portion 38a protruding from the surface 32b, and a jutted portion 38b jutted from a distal end of the vertical portion 38a toward the inner area. The resin layer 60 is formed in the inner area to cover a surface 38as of the vertical portion 38a facing the inner area as well as at least part of the jutted portion 38b.

Abstract: A conduction-breaking device breaks conduction between a pair of devices in an electric circuit. The conduction-breaking device includes a conductive body having a cuttable portion, an arc-extinguishing chamber having a pair of fixed blades, a gas generator, a cutting member having a pair of movable blades, and a deforming mechanism. When the cuttable portion is cut at two positions by the fixed blades and the movable blades, the cuttable portion forms a separated piece, which is separated from the electric circuit, and first and second remaining portions, which remain connected with the electric circuit. The separated piece has cut ends at opposite ends. The deforming mechanism deforms the separated piece such that the cut ends of the separated piece are located on a leading side in a moving direction of the cutting member with respect to a part of the separated piece between the cut ends.
