Cooling plate for fuel cell including coolant flow channels of constant flow rate

摘要

A cooling plate for a fuel cell is provided to cool the surface of a battery cell evenly by maintaining the constant flow rate of coolant flowing through respective coolant flow channels. A cooling plate(200) for a fuel cell including coolant flow channels of a constant flow rate has manifolds(210,220) at the inlet side and outlet side, and many coolant flow channels(230'). The length(L) of each coolant flow channel is controlled in proportion to a pressure normalization distribution function. The difference in pressure of the respective coolant flow channels is calculated by a computational fluid dynamic technique using geometric characteristic values of the cooling plate and inherent property values of a coolant.
