Provided is a film electrode assembly which can acquire unique information on a film electrode assembly even from the film electrode assembly alone. The film electrode assembly includes: a polymer electrolyte film; a pair of catalyst electrodes formed by a fuel pole and an air pole arranged to sandwich the polymer electrolyte film; and a unique information unit which contains unique information on the film electrode assembly. The unique information includes information on a catalyst composition of the catalyst electrode. More specifically, the unique information may be a content of Pt contained in the catalyst electrode.
