Abstract
A fuel cell 11, supply gas passages 12a, 12b which supply gas for power generation to the fuel cell 11, and an antifreeze passage 15 adjacent to the supply gas passages 12a, 12b via a partition 14 which selectively passes pure water installed in the fuel cell 11 or upstream of it, are provided, water is transferred from the antifreeze passage 15 to the supply gas passages 12a, 12b by the steam partial pressure difference between the antifreeze and supply gas at the partition 14, and the supply gas is thereby humidified.
Claims8
A fuel cell system, comprising:
- a fuel cell (11),
- a supply gas passage (12a, 12b) which supplies gas for power generation to the fuel cell (11), and
- a first antifreeze passage (15) adjacent to the supply gas passage (12a, 12b) via a partition (14) which selectively passes pure water from antifreeze, the partition (14) being installed inside the fuel cell (11) or upstream from the fuel cell (11),
- wherein water is transferred to the supply gas passage (12a, 12b) from the first antifreeze passage (15) by the difference of the steam partial pressure of the antifreeze and the steam partial pressure of the supply gas at the partition (14), and the supply gas in the supply gas passage (12a, 12b) is thereby humidified.
