The present disclosure pertains to a system () comprising a plurality of power converters (-to-n) configured, via a processing device (), to balance heat from a plurality of fuel cell stacks (-to-n). Some embodiments may: set one or more parameter values of one of the power converters (-) located at the output of one of the plurality of stacks (-) such that the one stack preferentially provides power to a load; determine a heat power of the one stack (-) and of one or more other stacks of the plurality of stacks (-to-n), each of the heat powers being determined based on a voltage and current that are determined at the input of the respective power converter (-to-n); determine whether the heat power of the one stack (-) satisfies a criterion; and responsive to a determination that the heat power of the one stack satisfies the criterion, set one or more parameter values of each of the power converters (-to-n) located at the output of the one or more other stacks such that the determined heat power of each of the one or more other stacks (-to-n) more closely matches the determined heat power of the one stack (-).
