Fuel cell stack, method for manufacturing fuel cell stack, and method for replacing modules constituting fuel cell stack

摘要

The fuel cell stack includes a first module that includes an electrolyte membrane, an anode, and a cathode, and a second module that includes a separator and is disposed adjacent to one surface of the first module via a first seal member. And a third module that is disposed adjacent to the other surface of the first module via the second seal member including the separator. In such a fuel cell stack, the peel strength of the first seal member with respect to the first module is higher than the peel strength with respect to the second module, and the peel strength of the second seal member with respect to the first module is third. Higher peel strength than module.
