Abstract:
The disclosure relates to a fuel cell stack and corresponding method of operating the fuel cell stack. The method comprises: determining a maximum allowable current that may be drawn from the fuel cell stack; repeatedly determining a magnitude of change to the prevailing maximum allowable current based on a prevailing allowable current ramp rate and an actual measured current of the fuel cell stack; updating the maximum allowable current according to the periodically determined magnitude of change; and controlling operating parameters of the fuel cell stack according to the prevailing maximum allowable current.

Claim (Index 10):
The method of  claim 1  further including determining the maximum allowable current as a function of one or more of:\n (i) a total system running time; \n (ii) a count of the total number of full stop-start cycles to which the fuel cell system has been subjected; \n (iii) an ambient humidity falling below a predetermined low humidity threshold; \n (iv) an ambient temperature falling below a predetermined low temperature threshold; \n (v) an ambient temperature rising above a predetermined high temperature threshold; \n (vi) a system voltage; \n (vii) the proximity of one or more cell voltages to a minimum cell voltage threshold and/or the proximity of a system temperature to a maximum temperature limit; and, \n (viii) the maximum allowable current does not fall below a predetermined minimum current limit.
