... explore how edge cooling with three different fin designs—one standard rectangular fin and two triangular fins that essentially halve the size of the fins—can improve the thermal and water envelopes inside the stack as well as stack performance while reducing the overall volume. The results suggest...

...: Convection, conduction, evaporation and condensation, Ohmic heating, entropy generation, and irreversibilities due to electrochemical reactions in the fuel cell stack are considered. Furthermore, convection and conduction without any heat generation is considered in the ambient; for the fins, we consider...
