Abstract
Membrane modules for hydrogen separation and fuel processors and fuel cell systems including the same are disclosed herein. The membrane modules include a plurality of membrane packs. Each membrane pack includes a first hydrogen-selective membrane, a second hydrogen-selective membrane, and a fluid-permeable support structure positioned between the first hydrogen-selective membrane and the second hydrogen-selective membrane. In some embodiments, the membrane modules also include a permeate-side frame member and a mixed gas-side frame member, and a thickness of the permeate-side frame member may be less than a thickness of the mixed gas-side frame member. In some embodiments, the support structure includes a screen structure that includes two fine mesh screens. The two fine mesh screens may include a plain weave fine mesh screen and/or a Dutch weave fine mesh screen. The fine mesh screens may be selected to provide at most 100 micrometers of undulation in the hydrogen-selective membranes.
