Abstract
A fuel cell assembly includes a manifold having a plurality of fuel cell connecting zones. At least some of the zones have differing characteristics such as area and arrangement of electrical connections and inlet and outlet ports corresponding to differing electrical power capacities. The assembly also includes one or more fuel cell stacks. At least some of the stacks have differing electrical power capacities, differing characteristics corresponding to the differing characteristics of the manifold zone, and corresponding differing arrangements of electrical connections and inlet and outlet ports. These differing characteristics are designed so that a fuel cell stack of a particular capacity can be connected only to a manifold zone corresponding to such capacity.
Claims14
A fuel cell assembly comprising:
- a manifold having a first fuel cell connecting zone having a first characteristic and at least a second fuel cell connecting zone having a second characteristic, the first characteristic being different from the second characteristic, each zone having coolant, fuel and air inlet and outlet ports, the manifold having a plurality of passages therein communicating with said ports;
- a first group of fuel cells coupled together to form a first fuel cell stack having a first electrical power capacity, the first stack being adapted to be operatively coupled to said first zone of the manifold and to the coolant, fuel and air inlet and outlet ports associated with said first zone;
- and
- at least a second group of fuel cells coupled together to form a second fuel cell stack having a second electrical power capacity which differs from the first electrical power capacity, the second stack being adapted to be coupled to said second zone of the manifold and to the coolant, fuel and air inlet and outlet ports associated with said second zone, the first zone characteristic being such that only a fuel cell stack having said first capacity can be coupled thereto, and the second zone characteristic being such that only a fuel cell stack having said second capacity can be coupled thereto, the first and second characteristics compising first and second different spacings of inlet or outlet ports.
