Systems and methods for fueling (or charging) communication, for example between a hydrogen fueling station and a hydrogen powered vehicle (or an electric vehicle and charging station) may utilize near field communication as well as vehicle to infrastructure communication. Safety information, fueling or charging information, payment information, and other information may be transmitted, and the redundant nature of the communication permits fault recovery and improved process monitoring. In this manner, fueling and/or recharging is made safer, faster, and more efficient.

Electric power is produced in a fuel cell array based on chemical fuel provided from a fuel source. The electric power is held available via an output terminal. A sensor cell registers a sensor signal reflecting a degree of consumption of chemical fuel in the fuel cell array relative to an amount of chemical fuel received in the fuel cell array. The production of electric power in the fuel cell array is monitored by measuring at least one voltage in the fuel cell array. A fraction of the electric power produced by the fuel cell array is controlled to be fed into a dynamic electric load connected to the output terminal. The fraction fed into the dynamic electric load is controlled in response to the sensor signal such that a difference is minimized between the amount of chemical fuel received in the fuel cell array and an amount of chemical fuel consumed in the fuel cell array when producing the electric power.
