1. A method of implementing power from first and second power sources in a fuel cell powertrain system, the method comprising:
receiving an input into a processor of the fuel cell powertrain system;
determining an output by the processor;
communicating the output by the processor to a system controller;
determining a power split by the system controller, the power split comprising:
a first power associated with the first power source, and
a second power associated with the second power source; and
implementing the power split,
wherein the first power source is a fuel cell system and the second power source is a battery system, wherein the power split is based on the input, and wherein the input is a system transient limit of the fuel cell system, number of starts and/or stops per hour of the fuel cell system, or time allowed at peak power of the fuel cell system.
