COOLANT MANIFOLD, COOLANT SUPPLYING METHOD AS WELL AS COOLANT DISCHARGING METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a coolant manifold capable of cooling efficiently a fuel cell stack by installing on the fuel cell, and a coolant supplying method and a coolant discharging method. PSOLUTION: The coolant manifold 1 is installed on the fuel cell stack 50 in which a plurality of unit cells 51 are laminated and which has a plurality of coolant supplying communicating holes 50e and coolant discharging communicating holes 50f, and coolant flows in order in the plurality of coolant supplying communicating holes 50e, the plurality of unit cells 51, and the coolant discharging communicating holes 51f, and distributes the coolant in the plurality of coolant supplying communicating holes 50e. The manifold 1 has a manifold main body 10 having a manifold chamber 11 communicated to the plurality of coolant supplying communicating hole 50e and an external communicating part 20 having an external communicating hole 21 to communicate the manifold chamber 11 and the outside. The axis A1 passing through the center of the external communicating hole 21 and the axis A2 passing through the center of each coolant supplying communicating hole 50e are un-parallel and non-perpendicular.
