Abstract

The present invention relates to a reinforced composite membrane for a water electrolysis cell, a membrane-electrode assembly for a water electrolysis cell, comprising same, and a water electrolysis cell comprising same, wherein in the reinforced composite membrane for a water electrolysis cell, a porous support is arranged to be biased toward the surface adjacent to an oxygen evolution electrode before operation of the water electrolysis cell, on the basis of a prediction of the area that expands after the operation, the oxygen evolution electrode undergoing relatively greater expansion, thereby evenly distributing the expansion stress applied to the reinforced composite membrane for a water electrolysis cell after operation and improving the performance and durability of the membrane-electrode assembly and water electrolysis cell comprising same.
