Claim:
1. A hydrogen purification device, comprising: first and second end frames including: first and second hydrogen-selective membranes disposed between and secured to the first and second end frames, the first and second hydrogen-selective membranes each having a feed side and a permeate side, at least part of the permeate stream being formed from the portion of the mixed gas stream that passes from the feed side to the permeate side, with the remaining portion of the mixed gas stream, which remains on the feed side, forming at least part of the byproduct stream; and a plurality of frames disposed between (1) the first end frame and the first hydrogen-selective membrane, (2) the first hydrogen-selective membrane and the second hydrogen-selective membrane, and (3) the second hydrogen-selective membrane and the second end frame, each frame of the plurality of frames including (i) a perimeter shell defining an open region and a frame plane and (ii) at least a first membrane support structure extending into the open region, wherein each of the at least a first membrane support structure is co-planar, within a first membrane support plane, with all other first membrane support structures of the plurality of frames, the first membrane support plane being perpendicular to the frame plane of each frame of the plurality of frames.
