System Stability and Performance Improvement with Anode Heat Exchanger Plumbing and Re-Circulation Rate |
摘要 |
A fuel cell system that increases stack stability by reducing the amount of liquid water droplets at the anode input of a fuel cell stack in the system. Re-circulated anode exhaust gas from the fuel cell stack and fresh hydrogen gas are sent to an anode heat exchanger so that both the fresh hydrogen gas and the re-circulated anode exhaust gas are heated to reduce the formation of water droplets in the anode input gas. Further, a portion of the heated cooling fluid directly from the fuel cell stack is sent to the heat exchanger to heat the fresh hydrogen gas and the re-circulation hydrogen before the cooling fluid is sent to an isolation heat exchanger to have its temperature reduced.
