Abstract

The present disclosure relates to a membrane-electrode assembly for a water electrolysis cell and a water electrolysis cell comprising same, wherein the membrane-electrode assembly for a water electrolysis cell further comprises a coating layer positioned on one surface of a catalyst layer to prevent an ion conductor exposed on the surface of the catalyst layer from contacting a microporous layer, and a polymer electrolyte membrane exposed through an opening in which the catalyst layer does not exist due to low loading from contacting the microporous layer, thereby reducing a band bending phenomenon, so that a pinch-off effect can be reduced and performance can be improved. In addition, furthermore, the coating layer serves to connect catalyst layers, which are not in contact with the microporous layer, to each other, thereby enabling smooth electron movement.
