Stack i.e. fuel cell stack, for conditioning hydrogen cells in electric drive of e.g. passenger car, has form-closure element fastened at stack independent another form-closure element to hold stack-bodies together in stack

摘要

The stack (1) has two retaining units (5, 6) for retaining respective form-closure elements (9, 10) that are respectively arranged at ends (E1, E2) of a tension-band device (7) i.e. metal-strip. The stack is formed as a ceramic assembly by stacking plate-shaped stack-bodies (2) i.e. ceramic components, into stacking direction (R). One of the form-closure elements is fastened at the stack independent of the other form-closure element in order to tension the band-device at an outer side (A) of the stack into the stacking direction and to hold the stack-bodies together in the stack. The form-closure elements are designed as a threaded rod and an anchor device. The retaining units are designed as a hole and a recess.
