摘要： An electrochemical device is provided, including a stack of a plurality of electrochemical units, at least one medium channel extending along a stack direction, at least one flow field via which a medium is able to flow transversely to the stack direction from the medium channel to another medium channel, and at least one connecting channel via which the flow field and the medium channel are in fluidic connection. The connecting channel has a medium channel-side mouth opening extending along a circumferential direction of the flow field from a first medium channel-side rim to a second medium channel-side rim, and a flow field-side mouth opening extending along the circumferential direction from a first to a second flow field-side rim. At least one of the flow field-side rims is offset away from the respective other flow field-side rim along the circumferential direction in relation to one of the medium channel-side rims.

摘要： To provide a flow element which in particular is used as a component of a bipolar plate in electrochemical devices, which is stable and permits efficient flow guiding, it is proposed that the flow element comprises a plate-like main body that is formed as a shaped sheet metal product and has a channel structure, wherein the channel structure comprises a plurality of channels which are formed by recesses in the main body and are separated from one another by raised portions of the main body, wherein there is provided at least one region with normal level difference that defines, with respect to a height direction running perpendicular to two main directions of extent of the main body, a height difference between a recess and an adjoining raised portion, wherein there is provided at least one region with reduced level difference, in which a height difference between a recess and an adjoining raised portion is less than the normal level difference, wherein the at least one region with reduced level difference comprises a parallel expansion region of the main body that, in the event of an expansion of the main body resulting from the deformation of the shaped sheet metal product, is expanded along expansion vectors which lie in mutually parallel planes, wherein the at least one region with reduced level difference, that comprises the parallel expansion region of the main body, adjoins a curvature expansion region of the main body which, in the event of an expansion of the main body resulting from the deformation of the shaped sheet metal product, is expanded along expansion vectors which lie in intersecting planes.

摘要： A fuel cell device is provided, including a fuel cell stack, which includes a plurality of fuel cell units following each other in a stacking direction, and two end plates, between which the fuel cell stack is arranged. With the fuel cell device, harmful effects from hydrogen exiting the fuel cell units are avoided without making access to the fuel cell units impossible or causing a disproportionately large maintenance expenditure. The fuel cell device includes an enclosure which surrounds the fuel cell stack and the end plates, wherein the free remaining volume that remains within the enclosure between the enclosure, the fuel cell stack, and the end plates is less than 20% of the internal volume of the enclosure.
