Fuel cell system

A fuel cell system comprising:

• a fuel cell unit including a fuel cell, an anode flow path through which an anode gas is supplied to the fuel cell, a cathode flow path through which a cathode gas is supplied to the fuel cell, and a heat exchanger configured to heat the cathode gas to be supplied to the fuel cell;
• and
• a manifold attached to the fuel cell unit and configured to distribute and supply the cathode gas to the cathode flow path, wherein
• the cathode flow path includes a main flow path passing through the heat exchanger, a bypass flow path bypassing the heat exchanger and connected to the main flow path, and a partial reformation flow path through which a gas for partial oxidation reformation is supplied to the anode flow path, and
• the manifold is configured as a gas distribution member including, in order from an upstream side, a first flow path connected to the main flow path, a second flow path provided adjacent to the first flow path and connected to the bypass flow path, and a third flow path provided adjacent to the second flow path and connected to the partial reformation flow path, and includes a communication path including a first communication path configured to connect the first flow path and the second flow path, and a second communication path configured to connect the second flow path and the third flow path.
