A hybrid powertrain system includes a combustion engine, a battery buffer for storing electric energy by converting it onto chemical energy, which can be converted back into electrical energy when need, a fuel cell unit having multiple fuel cells each of which is an electrochemical energy conversion device that converts hydrogen and oxygen into water, producing electricity and heat in the process, a power level control unit for capturing electrical energy from the fuel cell unit for delivering zero power, full power, or any power level in between, and an...
What is claimed is: 1. A hybrid powertrain system comprising a combustion engine coupled to a motor to mechanically drive the motor; a battery buffer for providing power to electrically drive the motor; a solid oxide fuel cell unit having a plurality of fuel cells for providing power to electrically drive the motor; and a power transfer control unit disposed between the combustion engine and the motor for selectively providing (i) pure electric power directly from the battery buffer to the motor during a fuel cell warm up period wherein the fuel cell is...
