METHOD FOR MITIGATING RECOVERABLE VOLTAGE LOSS THROUGH HUMIDIFICATION CONTROL |
| 摘要 |
A system and method for recovering fuel cell stack voltage loss through humidification control. The method includes determining a rate of contamination addition to a surface of a fuel cell electrode in the fuel cell stack and determining a rate of contamination removal from the surface of the fuel cell electrode. The method compares the rate of contamination addition to the rate of the contamination removal to determine whether contaminant surface coverage of the electrode is increasing or decreasing and, if increasing, determines whether the amount of contamination of the electrode is above a predetermined value, where, if so, stack reconditioning through wet stack operation may be performed. |

1. A method for recovering fuel cell stack voltage loss, said method comprising:
determining a rate of contamination addition to a surface of a fuel cell electrode in the fuel cell stack; determining a rate of contamination removal from the surface of the fuel cell electrode in the fuel cell stack; comparing the rate of contamination addition to the rate of the contamination removal to determine whether contaminant surface coverage of the electrode is increasing or decreasing; and determining whether the amount of contamination of the electrode is above a predetermined value.
