Abstract
A fuel cell stack includes a first power output unit connected to a first terminal plate, the first power output unit including a first conductor, and a second conductor extending from the first conductor to the outside of an outer peripheral end of a first inner insulator in the state where the second conductor is placed between the first inner insulator and a first end plate. The second conductor is positioned inside of the first end plate in a stacking direction of a cell stack body.
Claims10
A fuel cell stack comprising a cell stack body comprising a plurality of power generation cells stacked together in a stacking direction, the power generation cells each including a membrane electrode assembly and a separator,
- wherein a terminal plate is provided at one end of the cell stack body in the stacking direction, an insulator is provided outside the terminal plate, and an end plate is provided outside the insulator,
- a power output unit configured to collect electrical energy generated in the power generation cell to an outside is electrically connected to the terminal plate,
- the insulator has a surface facing the cell stack body, and a seal part configured to prevent leakage of fluid is provided on the surface, the seal part being provided around the terminal plate, and
- wherein the power output unit comprises:
- a first conductor extending to penetrate through the insulator in the stacking direction;
- and
- a second conductor extending from the first conductor to an outside of an outer peripheral end of the insulator in a state where the second conductor is placed on the insulator on an opposite side to the cell stack body, and
- the second conductor is positioned inside the end plate in the stacking direction of the cell stack body.
