Abstract: The present disclosure is directed to a system and method for reducing current variability between a plurality of energy storage devices, e.g. battery modules. In one embodiment, the method includes determining a resistance of at least two of the plurality of energy storage devices. Another step includes modifying an operating temperature of one or more of the plurality of energy storage devices when the resistance of one or more of the energy storage devices is outside of a predetermined tolerance range for the energy storage devices. Thus, the step of modifying the operating temperature of one or more of the plurality of energy storage devices causes the plurality of energy storage devices to operate within the predetermined tolerance range.

Abstract: A method and system for forming a hydrogen-rich reactant stream for use in a fuel cell is disclosed. The method comprises combining a hydrocarbon fuel with water to form humidified fuel and then pressurizing the humidified fuel. The pressurized, humidified fuel is then introduced to a fuel processor to produce a hydrogen-rich reactant for a fuel cell. By humidifying fuel prior to pressurization, a lower temperature of the water may be used compared to the temperature of the water required for humidifying pressurized fuel, thereby providing a more efficient method of producing a hydrogen-rich reactant for a fuel cell. Systems for effecting this method are also disclosed.
