Original Abstract Submitted

A fuel cell system, e.g., of a motor vehicle, includes a fuel cell stack having fuel cells and non-repeating hardware components, the latter including wet and dry end units. The cells are positioned between the end units. The dry end unit includes an end plate and a compression plate assembly that uniformly compresses the cells against the end plate, and a terminal plate surrounded by a seal plate. An insulator frame disposed adjacent to the compression plate assembly is engaged with the insulator frame via a frictional interface provided by o-ring compression seals having a respective post connected to the terminal plate and the seal plate, and a pocket connected to the insulator frame. The post and pocket of at least one of the compression seals together define a fluid passage. One or more shim plates may be disposed between the end plate and insulator frame.
