Fuel cell and method for manufacturing the same

A fuel cell comprising:

• a solid electrolyte membrane;
• a plurality of first electrodes having a first catalyst layer, provided on one face of said solid electrolyte membrane;
• and
• a plurality of second electrodes having a second catalyst layer provided on the other face of said solid electrolyte membrane and facing said plurality of first electrodes, respectively, wherein:
• a unit cell is configured by one of said first electrodes, one of said second electrodes and said solid electrolyte membrane, said one of said first electrodes and said one of said second electrodes being facing each other;
