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.
Claims16
A fuel cell block, comprising:
- a stack formed of a plurality of elements and axial passages formed through said elements in a stack direction;
- at least two adjacent said elements defining a space therebetween and a plurality of radial passages, communicating with said space and being formed between said two elements or in one of said two elements;
- a plurality of said radial passages connecting said space to at least one of said axial passages for exchanging fluid medium between said at least one axial passage and said space, and at least one of said radial passages forming a blind passage not forming a connection to a respective said axial passage.
A fuel cell block, comprising:
- a stack formed of a plurality of elements and axial passages formed through said elements in a stack direction;
- at least two adjacent said elements defining a space therebetween;
- said elements defining a plurality of radial passages including radial passages fluidically connecting said space with at least one of said axial passages for exchanging fluid medium between said axial passage and said space, and at least one blind radial passage that is closed and does not form a fluidic connection between said space and one of said axial passages.
