A hydrogen-selective membrane including a metal leaf applied to a substrate. A system and method for fabricating a hydrogen-selective membrane, including applying a metal leaf to a substrate, annealing the metal leaf, applying a hydrogen-permeable metal to the annealed metal leaf on the substrate, and annealing the hydrogen-permeable metal and the annealed metal leaf to give an alloy of the hydrogen-permeable metal and the metal leaf. A system and method for repairing a hydrogen-selective membrane having defects including applying a metal leaf to an external surface of membrane material of the hydrogen-selective membrane, annealing the metal leaf and metal of the membrane material to form an alloy of the metal leaf and the metal to repair the defects.

A filtration system can comprise a pressure pump configured to apply a pressure on fluid flowing between a first chamber and a second chamber. The filtration system can also comprise a flow sensor configured to determine at least one parameter associated with fluid flowing across a membrane deposited between the first chamber and a second chamber. The filtration system can comprise a pressure sensor configured to determine pressure readings of the fluid flowing from the first chamber to the second chamber. The filtration system can comprise a filtration management system configured to cause the pressure pump to apply a constant pressure on fluid flowing across the membrane for a first predetermined time based on the pressure reading. The filtration management system can be configured to cause the pressure pump to reverse the fluid flow across the membrane.
