ABSTRACT:
A fuel cell stack is formed by a plurality of fuel cell blocks each of which comprises a plurality of fuel cell units laminated together. Each cell block has its own set of manifolds for supply and return of the reaction gases. Each manifold is insulated from the others and from the main gas line to which it is connected. When a cooling system is used, the various cooling elements are similarly electrically insulated from one another and from their main conduit.
