Manifold device of fuel cell stack

A manifold device of a fuel cell stack, comprising:

• a gas inlet and a gas outlet disposed at one end of the fuel cell stack;
• a gas supply path configured to supply a gas into the fuel cell stack having a plurality of cells stacked therein;
• and
• a gas discharge path configured to discharge the gas from the fuel cell stack and disposed apart from the gas supply path,
• wherein the gas supply path includes a gas heating part disposed in the fuel cell stack to heat the gas supplied into the fuel cell stack using heat of the fuel cell stack and vaporize liquid contained in the gas and a gas supply part configured to supply the gas flowing from the gas heating part to each cell of the fuel cell stack,
• wherein the gas heating part is not connected to gas channels of the plurality of cells and extends from the one end of the fuel cell stack to an opposite end of the fuel cell stack in a stacking direction,
• wherein the gas supply part and the gas discharge path are connected with each other by the gas channels of the plurality of cells and both of the gas supply part and the gas discharge path extend from the opposite end of the fuel cell stack to the one end of the fuel cell stack in a stacking direction,
• wherein the gas supplied from the gas inlet flows through the gas heating part in a first direction, the gas supplied into the gas supply part from the gas heating part flows through the gas supply part in a second direction opposite to the first direction and the gas supplied into the gas discharge path flows through the gas discharge path in the second direction, and
• wherein each of the gas channels of the plurality of cells is connected between the gas supply part and the gas discharge path such that each cell has about the same traveling distance of the gas.
