A disassembly method for membrane electrode assembly for fuel cell, and a disassembly method for fuel cell are provided, disassembly methods which are advantageous for the recovery of catalysts that are included in catalytic layers by making structural destruction of the catalytic layers progress by means of expanding a volumetrically-expandable material inside the catalytic layers. In such a state that a catalytic layer includes a volumetrically-expandable material that is capable of expanding volumetrically, the volumetrically-expandable material, which is included in the catalytic layer, is expanded by means of expansion treatment. Next, expansion of the volumetrically-expandable material, which has undergone volumetric expansion in the catalytic layer, is cancelled.
