Relative humidity profile control strategy for high current density stack operation |
摘要 |
A control strategy results in a relative humidity profile that is substantially the same or constant regardless of the operational power level of the fuel cell stack. The strategy maintains the relative humidity profile within a range that enables high current density operation of the fuel cell stack. The profile is achieved by adjusting a coolant flow rate through the fuel cell stack to maintain a temperature change across the coolant flow path from inlet to outlet substantially constant regardless of the operational power level of the fuel cell stack. |
