In this paper, the numerical method of heat transfer and fluid flow in the fuel cell of polymer membranes and cooling channels, with the parallel channel pattern and the use of liquid water in separate channels embedded in the bipolar plane, is investigated and the performance of four different field designs Gas flow and cooling, based on the absence of the need for an external thermal boundary condition, the temperature uniformity is simulated and compared using Ansys-Fluent software. The results showed that by increasing the Reynolds number of the cooling flow from 40 to 800, the pressure drop in the cooling flow channel path reaches from 40 to 640 Pascals. On the other hand, the Nusselt number of the cooling flow increases exponentially from 350 to about 700 by changing the Reynolds number from 40 to 400, and then it is fixed. The results also showed that the best cell performance was obtained at Reynolds number 60, because with increasing Reynolds number, the cooling flow and increasing pressure drop of the system’s noise power increases.
