A SYSTEM FOR PURGING NON-FUEL MATERIAL FROM FUEL CELL ANODES |
摘要 |
A fuel cell gas purge system is provided that includes at least one fuel cell, such as a fuel cell stack or a fuel cell array, a fuel supply, and an adjustable fuel cell current load. The system further includes at least one passive purge valve disposed to purge accumulated non-fuel matter in the fuel cell, and operates according to a pressure differential across the valve. The valve can be a passive bi-directional valve, such as a dome valve, or a passive unidirectional valve. Further included is a purge management module that has a purge request module to determine when to increase the pressure of the hydrogen fuel to initiate the purge, and a purge complete module to determine when to adjust the pressure of the hydrogen fuel to complete the purge. The non-fuel matter can include non-fuel gases or condensed water. |
