Abstract
A vane () at the juncture of orthogonal conduits () allows flow of air to and from the air inlet/outlet manifold () of a fuel cell stack () when it is disposed in a first position, and totally blocks the conduits () so as to isolate the air flow fields of the fuel cells () when in a position normal to the first position. A vane () can comprise the divider of the air inlet/outlet manifold when in a vertical position, and totally block off the manifold when in a horizontal position. A vane () can align with the divider () of an air inlet/out manifold when in a vertical position, and block the passage between the manifold and conduits () when in a horizontal position. Similar vanes may be used for single-valve selection of flow or containment of fuel reactant gas.
