Systems and methods for hydrogen generation via ammonia decomposition that utilize a fixed bed reactor configured to receive inflows of NH₃ and oxidant and to produce an outflow of high purity H₂. The fixed bed reactor contains a fixed bed of a NH₃ decomposition catalyst wherewith the NH₃ decomposes to form N₂ and H₂; a plurality of ceramic hollows fibers with a high surface to volume ratio disposed in the fixed bed, the hollow fibers having an H₂ selective membrane disposed thereon for extracting H₂ from N₂ and to form a permeate of the high purity H₂ and a retentate of primarily N₂; and a catalytic H₂ burner also disposed in the fixed bed, the catalytic H₂ burner for burning a portion of the H₂ with the oxidant to provide thermal energy for the NH3 decomposition.
