Abstract
A fuel cell system includes a first reactant intake manifold, a first reactant output manifold, a second reactant intake manifold, a second reactant output manifold, a cooling gas intake manifold, a cooling gas output manifold, a liquid intake manifold, fuel cells and a cooling elements distributed among the fuel cells. Each cooling element defines a coolant passage. During operation, a cooling gas flows from the cooling gas intake manifold into the cooling gas output manifold through the coolant passage. Each cooling element also includes a water injection path. During operation water from the liquid intake manifold is injected into the coolant passage to mix with the cooling gas passing therethrough.
