摘要： A fuel cell system according to the present invention comprises a fuel gas supply system that supplies a fuel gas from a fuel supply source to a fuel cell that includes a stack including a plurality of cells, and a fuel off-gas circulation system that resupplies fuel off-gas to the stack. The fuel off-gas circulation system includes: a mixed fuel gas flow path formed such that a mixed fuel gas containing the fuel off-gas and the fuel gas flows in a direction along an inner surface of a manifold installed in the stack; and a point of merger where the fuel off-gas and the fuel gas merge with each other to produce the mixed fuel gas, the point of merger being arranged on one surface side of the manifold. With such configuration, the heat exchange efficiency of the fuel off-gas and the fuel gas can be increased, and ice resulting from water in the fuel off-gas can be prevented from flowing into the fuel cell stack.

摘要： A fuel cell system to be mounted on an electric vehicle such as a hybrid vehicle or an electric vehicle. Cooling water is supplied from a cooling water inlet of a stack manifold, flows through a fuel cell stack, and returns to the stack manifold. A groove is formed on the rear surface side of the stack manifold, constituting, together with a terminal, a cooling water channel. The cooling water flows through the cooling water channel, and is discharged to the outside from a cooling water outlet. The cooling water channel is formed extending from the rear side to the front side of the vehicle, and warms an end plate. A pipe length of the cooling water channel to a radiator mounted in a front part of the vehicle is reduced.

摘要： A fuel cell system includes a fuel cell; a circulating system that circulates and supplies fuel off-gas discharged from the fuel cell to the fuel cell; a pump that pumps a fluid in the circulating system; a discharge valve through which the fluid in the circulating system is discharged to the outside; and a control device that controls the pump and the discharge valve. If operation of the fuel cell is started in a cold environment, the control device executes a control to start power generation in the fuel cell for a first period before activating the pump and executes a control to drive the pump while the discharge valve is closed for a second period.
