ABSTRACT:
The apparatus according to this invention is provided with a stack assembly composed of two kinds of cells disposed in such order of arrangement that the adjacent cells are different in kind from each other. A first cell includes a first fluid distribution means and a membrane lying on either side of said means. A second cell includes a second fluid distribution member that forms independent tunnel-like fluid paths between the membrane support sheet and respective ones of the paired members having a plurality of grooves on one surface thereof, said membrane support sheet being provided with a large number of projections on the central portion thereof and said pair of grooved members being arranged so that the grooved surfaces are face-to-face with each other, interposing said membrane support sheet therebetween. In order that each of said distribution members may introduce a respective fluid separately through said stack assembly and said first fluid may be distributed between a pair of membranes composing the first cell as well as the second fluid distributed between the second cell and adjacent membrane, the fluid manifolds of all of said cells communicate with the inlet and outlet ports for the first and second fluids and are arranged so as to perform substantially uniform diffusion exchange of substances between said first and second fluids.
