FUEL CELL FLUID DISCHARGE SYSTEM, A FUEL CELL SYSTEM, AND A METHOD FOR DISCHARGING BYPRODUCTS PRODUCED DURING FUEL CELL OPERATION

A fuel cell fluid discharge system, a fuel cell system, and a method for discharging byproducts produced during fuel cell operation are provided. The fluid discharge system comprises an inlet port, a discharge port, and a vessel. The vessel comprises a vessel port and an adjustable wall. The adjustable wall forms a fluid tight seal between a first volume within the vessel partially bounded by a first side of the adjustable wall, and a second volume of the vessel partially bounded by a second side of the adjustable wall. Moving the adjustable wall from a second position to a first position draws fluid through the inlet port into the first volume. Moving the adjustable wall from the first position to the second position expels fluid through the discharge port from the first volume at a pressure greater than a reactant pressure of the fuel cell.
