ABSTRACT:
The fuel cell block has stacked elements. At least two adjacent elements define an intermediate space between them. Radial channels are formed between the two elements or in one of the elements. The radial channels connect the space to an axial channel through the stack. At least one of the radial channels is a blind channel which, in contrast with the other radial channels, does not allow fluid communication between the space and the axial channel. The number of radial channels that are configured as blind channels influences the quantity of operating medium flowing through the intermediate space.
