A unit cell (10) of a fuel cell includes an electrolyte electrode assembly (MEA) (12), a pair of separators (14, 16) sandwiching the MEA (12), and a buffer layer (22) at least provided between the MEA (12) and at least one of the separators (14, 16). The buffer layer (22, 24) is made of porous body formed by melting inorganic powder. A buffer layer precursor (18, 20) contains the inorganic powder and an organic material, and the organic material is vaporized from the buffer layer precursor (18, 20) to obtain the buffer layer (22, 24). The buffer layer (22, 24) fills clearance between projections (32) of the separator (14) and the anode (26) or the cathode (30), and tightly contacts the projections (32) of the separator (14) and the anode (26) or the cathode (30). |
