Abstract
A fuel gas supply path in a fuel cell stack includes in series a first path, a second path, and a third path. In the second path, two inlets of the fuel gas in each of power generating cells included in the second path are located at a first position PA and a second position PB, and the position of one outlet of the fuel gas in each power generating cell is located at a third position PC. In the third path, an inlet of the fuel gas in each of power generating cells included in the third path is located at a position coinciding with the third position PC when the power generating cells are viewed in the stacking direction, and an outlet of the fuel gas in each power generating cell is located at a position between the first position PA and the second position PB.
