Significance Palladium‐based membranes are currently the most advanced membranes for hydrogen separation and are on the verge of practical application. However, the search for alternative membranes continues in an effort to lower their cost and susceptibility to poisons. Here for the first time we report a novel sandwiched liquid metal membrane (SLiMM) for hydrogen separation. Permeation experiments indicate that the Ga/SiC SLiMM has a permeability of 2 . 75 ×10 − 7 mol / ms ⋅Pa 0 . 5at 500°C, which is 35 time higher than that for Pd under similar conditions. This promises a potential for application of SliMM in hydrogen purification. © 2016 American Institute of Chemical Engineers AIChE J , 63: 1483–1488, 2017
