The fuel cell device includes an enclosure which surrounds the fuel cell stack and the end plates, wherein the free remaining volume that remains within the enclosure between the enclosure, the fuel cell stack, and the end plates is less than 20% of the internal volume of the enclosure. | 2020-05-14 |
