Claim Text:
1. A fuel cell assembly, comprising: a stack of fuel cell component elements having a first end opposite to a second end and a first side, a second side, a third side, and a fourth side that each extend between the first and second ends; a first end plate adjacent to the first end of the stack of fuel cell components; a second end plate adjacent to the second end of the stack of fuel cell components; a first oxidant reactant manifold adjacent to the first side of the stack of fuel cell components; a second oxidant reactant manifold adjacent to the second side of the stack of fuel cell components; a first fuel reactant manifold adjacent to the third side of the stack of fuel cell components; and a second fuel reactant manifold adjacent to the fourth side of the stack of fuel cell components, ends of the first oxidant reactant manifold overlapping a first side of the first fuel reactant manifold and a first side of the second fuel reactant manifold, ends of the second oxidant reactant manifold overlapping a second side of the first fuel reactant manifold and a second side of the second fuel reactant manifold, the first oxidant reactant manifold including a first inboard side flange that divides the first oxidant reactant manifold into a first oxidant reactant chamber and a first coolant chamber and a second inboard side flange that divides the first oxidant reactant manifold between the first oxidant reactant chamber and a second coolant chamber, wherein the first coolant chamber and the second coolant chamber are laterally outward of the first oxidant reactant chamber, the second oxidant reactant manifold including a third inboard side flange that divides the second oxidant reactant manifold into a second oxidant reactant chamber and a third coolant chamber and a fourth inboard side flange that divides the second oxidant reactant manifold between the second oxidant reactant chamber and a fourth coolant chamber, wherein the third coolant chamber and the fourth coolant chamber are laterally outward of the second oxidant reactant chamber, the first and second oxidant reactant manifolds and the first and second fuel reactant manifolds being positioned to prevent leakage of reactant from the stack and the manifolds to an external environment.
