1. A fuel cell device comprising:
- a fuel cell stack comprising;
a lower end plate;
an upper end plate;
a lower insulator plate and an upper insulator plate disposed vertically adjacent to the lower and upper end plates;
a lower current collector plate and an upper current collector plate disposed vertically adjacent to the lower insulator plate and an upper insulator plate;
a stack of fuel cells disposed between the current collector plates; and
at least one flexible enclosure in sealing contact with the end plates and enclosing the fuel cell stack.
