<p>A method of sealing a diffusion device having symmetrical stacked plates and associated diffusion membranes covering a side of each plate, the plates having fluid flow channels from end to end thereof adjacent opposed plate edges comprises sealing an end of each channel in each stacked plate, encasing the plates and membranes in a pair of hollow shells to enclose the plates, the shells defining peripheral flanges which abut one another when assembled, and molding about the outer periphery of the flanges a unitary integral retention member. The shells and flanges are held together until the retention member has hardened so that the member will hold the flanges together in firm, abutting relation.</p> |
