A dual-battery fuel cell system is provided, including two supplemental batteries, each battery supporting/supplementing operation of a fuel cell stack in the system. Driving conditions associated with a fuel cell vehicle can be obtained. Based on the driving conditions, power sources of the fuel cell vehicle to provide power to fuel cell vehicle system can be determined, the power sources comprising the fuel cell stack and the two supplemental batteries. Operating conditions of each of the power sources can be assessed, and one or more of the power sources can be controlled to deliver power to the fuel cell vehicle system based on the operating conditions of each of the power sources.
