PURPOSE: A fuel cell stack is provided to obtain a fuel cell having excellent power density per a volume and improved reliability and to be applied as a solid oxide fuel cell by including laminated multiple unit cells having a membrane electrode bonding unit and porous supporter. CONSTITUTION: A fuel cell stack(40) includes a first unit cells(10) and a second unit cells(20) which are laminated by turns. The first cell comprises a first membrane-electrode assembly(11) including a first electrolyte membrane(13) which is placed between a first cathode and a first anode and a first porous supporter(15) which is formed on the first anode. The second unit cell comprises a second membrane-electrode assembly including a second anode(22), a second cathode(24), and a second electrolyte membrane(23) which is placed between the second anode and the second cathode and a second porous supporter(25).
