Thermal energy recycling fuel cell arrangement

摘要

An example fuel cell arrangement includes a fuel cell stack configured to receive a supply fluid and to provide an exhaust fluid that has more thermal energy than the supply fluid. The arrangement also includes an ejector and a heat exchanger. The ejector is configured to direct at least some of the exhaust fluid into the supply fluid. The heat exchanger is configured to increase thermal energy in the supply fluid using at least some of the exhaust fluid that was not directed into the supply fluid.

1. A fuel cell arrangement comprising:
a fuel cell stack configured to receive a supply fluid and to provide an exhaust fluid that has more thermal energy than the supply fluid; an ejector configured to separate the exhaust fluid into a first exhaust fluid stream and a second exhaust fluid stream, and to direct the first exhaust fluid stream into the supply fluid, a mixture of the supply fluid and the first exhaust fluid stream being directly supplied from the ejector to the fuel cell stack; a heat exchanger configured to increases thermal energy in the supply fluid using the second stream of the exhaust fluid; and wherein the supply fluid and the exhaust fluid are air.
