However, their practical implementation as electrolytes in fuel cells has long been impeded by the difficulty of fabricating dense membranes, which leads to severe hydrogen crossover and a markedly reduced open circuit voltage (OCV) of only \u223c0.8\u2009V, far below the theoretical value. Here, we demonstrate for the first time a dense, free\u2013standing nanosheet\u2013stacked membrane of magnesium aluminum layered double hydroxide (MgAl\u2013LDH) prepared via an exfoliation\u2013reassembly strategy. The membrane exhibits an out\u2013of\u2013plane hydroxide ion conductivity of 0.0065\u2009S cm\n                    <jats:sup>\u22121<\/jats:sup>\n                    at 80\u00b0C and 100% RH, while its in\u2013plane conductivity reaches 0.22\u2009S cm\n                    <jats:sup>\u22121<\/jats:sup>\n                    , approximately 30\u2013fold higher, underscoring the intrinsic anisotropy of ion transport in LDH nanosheets. Remarkably, when employed in direct ethanol fuel cells, the MgAl\u2013LDH nanosheet membrane achieves an OCV of \u223c1.10\u2009V, indicating substantially suppressed fuel crossover compared with conventional LDH\u2013based electrolytes. This work establishes LDH nanosheet membranes as a new class of dense, high\u2010performance hydroxide ion conductors, overcoming a long standing barrier in LDH\u2013based electrolytes and paving the way for nanosheet\u2013stacked solid electrolyte fuel cells.\n
