1. A fuel cell vehicle, comprising:
a processor; and
a memory unit operatively connected to the processor, the memory unit including computer code that when executed causes the processor to:
determine whether a battery's state of charge (SOC) meets a maximum battery SOC threshold;
in response to a determination that the battery SOC meets the maximum battery SOC threshold, capture nitrogen gas byproduct of a fuel cell stack of the fuel cell vehicle; and
compress and store the nitrogen gas byproduct in a storage tank using regenerated energy in excess of the maximum battery SOC threshold.
