摘要 |
A method for purging non-fuel gasses from a fuel supply of a fuel cell system, including measuring a first parameter indicative of fuel concentration within the fuel supply, in response to the first parameter measurement satisfying a purge condition, wherein the purge condition is satisfied when the first parameter measurement is indicative of the fuel concentration below a predetermined concentration threshold, opening a purge valve fluidly coupled to the fuel supply and generating a purging pressure within the fuel supply to purge the fuel supply, measuring a second parameter indicative of purge completion, and in response to the second parameter measurement satisfying a purge completion condition, closing the purge valve.
