1. A method of manufacturing a membrane-electrode assembly, the method comprising:
preparing an electrolyte sheet having a predetermined length and a predetermined width;
forming electrode groups on the electrolyte sheet in a plurality of rows in a lateral direction, each of the electrode groups being configured such that a plurality of electrodes is disposed spaced apart from each other by a predetermined distance in a longitudinal direction of the electrolyte sheet;
cutting the electrolyte sheet between the electrode groups to obtain a plurality of stacks located in different planes; and
joining sub-gaskets to opposite surfaces of each of the plurality of stacks.
