A fuel cell arrangement consisting of several fuel cells, arranged at least essentially in parallel, with cooling gaps formed between neighboring cells extending between an inlet and an outlet and through which a coolant flows, characterized by the fact that the specific surface, i.e. the area of the cooling surfaces emitting heat to the coolant, increases in the direction from the inlet to the outlet and/or that the local heat transfer coefficient of the cooling areas emitting heat to the coolant increases in the direction of flow from the inlet to the outlet and/or that the support materials of the fuel cells, i.e. the membrane-electrode assemblies, exhibit a coefficient of thermal conductivity above 200 W/(m ~ K). In this way, a uniform temperature in the fuel cells can be assured to that the power density can be increased while avoiding hot spots and/or the service life can be increased.
