FUEL CELL STACK, FUEL CELL STACK MANUFACTURING METHOD, AND METHOD OF EXCHANGING MODULES COMPRISING THE FUEL CELL STACK

A fuel cell stack includes: a first module configured to include an electrolyte membrane, an anode and a cathode; a second module configured to include a separator and placed adjacent to one surface of the first module via a first sealing member; and a third module configured to include a separator and placed adjacent to the other surface of the first module via a second sealing member. In this fuel cell stack, the first sealing member has the greater peel strength to the first module than the peel strength to the second module, and the second sealing member has the greater peel strength to the first module than the peel strength to the third module.
