Fuel cell system

A fuel cell system comprising:

• a plurality of fuel cell stacks each having a stack structure in which a plurality of fuel cells are stacked and each provided with a coolant flow path through which a coolant flows,
• wherein the plurality of fuel cell stacks are juxtaposed in a horizontal direction, and
• include a supply pipeline that distributes and supplies the coolant to the coolant flow path, and
• a discharge pipeline that collects and discharges the coolant that has flowed through the coolant flow path,
• wherein the fuel cell system further comprises the supply pipeline and the discharge pipeline are provided within a formation range where the coolant flow path is formed in the plurality of fuel cell stacks, in a direction of gravity,
• wherein the supply pipeline and the discharge pipeline extend from one end side to an other end side of the plurality of juxtaposed fuel cell stacks, and each of the supply pipeline and the discharge pipeline branches to be connected to the coolant flow path of each of the plurality of juxtaposed fuel cell stacks, and
• wherein the discharge pipeline is provided closer to the plurality of fuel cell stacks than the supply pipeline.
