Abstract
A fuel cell system having at least one fuel cell and a cathode loop for recycling a portion of an unused oxidant from the fuel cell for reuse in the same fuel cell is presented. The cathode loop may comprise an oxidant inlet manifold in the fuel cell configured to supply oxidant to the fuel cell, an oxidant exhaust manifold in the fuel cell configured to receive unused oxidant from said fuel cells, and a cathode ejector configured to receive oxidant from an oxidant source and the oxidant exhaust manifold and to supply oxidant to the oxidant inlet manifold, wherein a portion of said unused oxidant is supplied directly to said oxidant inlet manifold from said oxidant exhaust manifold via said cathode ejector.
