Coolant flow field design of fuel cell stack

摘要

The dipole plate assembly in order to use at the fuel cell stack which supplies the reactant on anode side and cathode side of the fuel cell within stacking is offered. This dipole plate assembly the surface of aforementioned 1st aspect which possesses the coolant flow place which was formed inside the surface of the 1st aspect and has the 1st and 2nd sub plate which has the surface of aforementioned 2nd aspect which possesses the reactant flow place which was formed inside the surface of the 2nd aspect respectively. The place of the coolant description above of the 1st and 2nd sub plate at that time has the respective flow resistance, has the territory where the fluid quantity differs. It becomes possible to obtain fixed temperature, depending upon the territory where this fluid quantity differs, fuel cell stack variable cooling which extends over to become possible, over fuel cell stacked the whole with this.
