A clamp assembly 1 for securing a fuel cell stack arrangement in a compressed condition is disclosed. The stack 2 includes an electrode assembly 10 interposed between upper 20 and lower 25 current collectors, supportable between upper 30 and lower 50 endplate structures. The clamp assembly comprises at least one rigid clamping device 60, 70, 80, 90 comprising spaced apart transversely disposed elongate clamp members for engaging outer surfaces of the upper 30 and lower 50 endplates respectively along peripheral edges, the clamp members 60, 70, 80, 90 being separated by vertically disposed support members having a length greater than the height of the stack 2 in a compressed condition thereof. The endplate structures define docking formations 35a, 35b, 36a, 36b (upper endplate 30) and 55a, 55b, (56a, 56b; not shown) (lower endplate 50) along peripheral edges for engaging the clamp members under compression of the stack. The docking formations define spaces between the endplate structures and the compressing means , e.g. machine press (200, figure 4) within which spaces the clamp members are receivable during compression. Upon release of compression, the clamp members 60, 70, 80, 90 remain captively engaged within the docking formations 35a, 35b, 36a, 36b (upper endplate 30) and 55a, 55b, (56a, 56b; not shown) (lower endplate 50) against recoil pressure of the stack. A method of using the clamp assembly 1 is also claimed. |
