Abstract
A vehicle includes a fuel cell stack arranged to generate power for propulsion, an auxiliary fuel cell stack component, and a processor. The processor, responsive to a crowdsourced average value of an operating parameter of an auxiliary fuel cell stack component of other fuel cell vehicles being different, for a pre-defined power level, than an average value of a same operating parameter of the auxiliary fuel cell stack component by a pre-determined amount, purge the fuel cell stack of nitrogen.
Claims19
A vehicle comprising:
- a fuel cell stack arranged to generate power for propulsion;
- an auxiliary fuel cell stack component;
- and
- a processor programmed to, responsive to a crowdsourced average value of an operating parameter of an auxiliary fuel cell stack component of other fuel cell vehicles being different, for a pre-defined power level, than an average value of a same operating parameter of the auxiliary fuel cell stack component by a pre-determined amount, purge the fuel cell stack of nitrogen.
A vehicle comprising:
- at least one fuel cell stack arranged to generate power for propulsion;
- an auxiliary fuel cell stack component;
- and
- a processor programmed to
- for a predefined power level that is at idling of the at least one fuel cell stack, transmit data off board indicative of an average value of an operating parameter of the auxiliary fuel cell stack component, and
- receive a command to schedule a service event.
A data processing unit comprising:
- a processor programmed to
- collect real time data indicative of, for each of a plurality of fuel cell powered vehicles, an operating parameter of an auxiliary fuel cell component, and
- command a service event for at least one of the vehicles responsive to the at least one having an average operating parameter value different than an average value of the operating parameters of the plurality of fuel cell powered vehicles by an amount greater than a predefined threshold.
