A system block (10) for mounting one or more cell stacks consists of two opposed half-blocks (12, 14) between which is sandwiched at least one separation plate (16). Each half-block (12, 14) comprises a flat plate and a multiplicity of protruding ribs. The ribs may be formed by injection moulding. The protruding ribs on an inner surface, that is a surface that faces the separation plate, define flow channels for fluids, while protruding ribs (20) on an opposite, outer surface of a half-block (12) define locating recesses or sockets for connection to cell stacks or to fluid flow ducts. At least some of the flow channels communicate with apertures in the flat plate of the half-block or apertures in the separation plate (16), and the cell stacks communicate with some of these apertures. The system block (10) enables fluids such as liquid electrolyte, hydrogen and air, to be supplied to and removed from one or more fuel cell stacks, while only requiring a single external connection for each fluid to or from the system block. |
