A stator for an electric machine, including a shaped rod winding, wherein the shaped rod winding is formed by a plurality of shaped rods which have connecting points in the region of a winding head, wherein the connection points are surrounded by a casting layer, and wherein a thickness of the casting layer is predetermined by an enveloping element which is arranged on the winding head close to the contour.

Stator for an electric machine

An interconnection device for an electric machine, in particular for an electric machine for a motor vehicle, is provided for interconnecting shaped-bar ends of a winding, in particular of a stator winding. The interconnection device has an interconnection element, which has one or more openings for the insertion of at least one shaped-bar end, wherein the one or more openings each have an insertion section and a contact-making section adjoining the insertion section, which sections are designed such that the at least one shaped-bar end can be inserted into the insertion section and, in the case of a relative movement between the opening and the inserted shaped-bar end, the inserted shaped-bar end reaches the contact-making section and the spacing between the at least one shaped-bar end and a contact is reduced by way of being guiding through the contact-making section.

Interconnection device for an electric machine

A fuel cell arrangement is disclosed. The fuel cell arrangement includes a fuel cell stack and a housing wall element to form a housing surrounding the fuel cell stack. The housing wall element comprises a penetrating opening for an electric contacting of the fuel cell stack via a conductor. The conductor extends through the penetrating opening. A sheath is arranged between the penetrating opening wall and the conductor around an insulation layer arranged at the conductor. The sheath, together with the insulation layer, is pushed against the conductor in a gas-tight fashion, with the penetrating opening being sealed in a gas-tight fashion via a compensation element to compensate for longitudinal and lateral movements. The compensation element is lastingly fastened at the sheath element and the housing wall element in a gas-tight fashion.

Fuel cell arrangement

There is disclosed a fuel cell assembly comprising at least one horizontally arranged fuel cell stack that has numerous fuel cells, each comprising an anode, a cathode and an electrolyte situated between the anode and the cathode; combustible gas supply means for supplying combustible gas to the anodes of the fuel cells; anode gas withdrawal means for withdrawing the anode exhaust gas from the anodes; cathode gas supply means for supplying cathode gas to the cathodes of the fuel cells; cathode gas withdrawal means for withdrawing the cathode exhaust gas from the fuel cells; and recirculation means for recirculating at least one part of the anode exhaust gas and/or the cathode exhaust gas to cathodes of the fuel cells. The fuel cell assembly according to the invention is characterized in that the recirculation means comprise at least one catalytic burner with catalyst material for burning the remaining combustible gas contained in the anode exhaust gas, said burner being situated at the side of the fuel cell stack.

Fuel cell assembly comprising an improved catalytic burner

The invention relates to a sealing device for a fuel cell arrangement having a plurality of fuel cells combined to form a fuel cell stack (), said fuel cells being permeable by the gas flows converted in the fuel cells transversely to the longitudinal direction of the fuel cell stack (), and a gas distributor () provided on the longitudinal side of the fuel cell stack () for the supply and removal of the gas flows converted in the fuel cells, wherein the sealing device comprises a sealing frame () having a number of longitudinal sealing elements () disposed between the longitudinal edge of the gas distributor () and the fuel cell stack () and composed of a dielectric material, said sealing elements being disposed in a longitudinally movable fashion for the compensation of particularly thermally caused relative movements between the fuel cell stack () and the gas distributor (). According to the invention, the longitudinal sealing elements () are closely disposed one next to the other in a gap-free fashion on the face, and a tension system having tension devices () is provided for producing a mechanical tension pressing the longitudinal sealing elements () together in the longitudinal direction between the ends of the sealing frame ().
