Abstract
A fuel cell assembly according to an exemplary aspect of the present disclosure includes, among other things, a first fuel cell stack in series with a variable resistor and a second fuel cell stack in parallel with the first fuel cell stack and in series with a contactor. A resistance level of the variable resistor is adjusted in response to deactivating the contactor. A method of regulating a fuel cell assembly is also disclosed.
Claims20
A method of regulating a fuel cell assembly, comprising:
- generating a high power in a high power range using a first fuel cell stack and a second fuel cell stack in parallel with each other;
- generating a low power in a low power range using said first fuel cell stack, said second fuel cell stack being deactivated in said low power range;
- and
- wherein a resistance within a path defined by said first fuel cell stack changes in response to transitioning between said low and high power ranges, thereby maintaining said low power and said high power within a single voltage range.
