Temperature distribution

Optimization of the temperature distribution in fuel cells

During the operation of fuel cells, heat is produced as the result of activation losses and ohmic losses. The efficiency of PEM fuel cells is tpyically about 50 %, which means that the fuel cell produces as much heat as electrical energy. The waste heat has to removed from the fuel cell. At the same time, the temperature in the cell has to be as uniform as possible to guarantee the optimal perfomance. Temperature gradients result in locally differing reaction rates, hot spots and thermal stresses, which can result in damaging of the fuel cell.

The cooling channles of a LTPEM fuel cell are designed using computational fluid dynamics (CFD).
