Abstract
A hydrogen hybrid locomotive including a set of batteries for driving a plurality of electric traction motors for moving the locomotive along a set of railroad rails and a fuel cell power plant for charging the set of batteries and driving the electric traction motors. The fuel cell power plant includes at least one fuel cell power module for generating electrical current by reacting hydrogen fuel and oxygen from intake air, the amount of electrical current being proportional to an air mass flow of the intake air. An air system selectively provides an air mass flow to the fuel cell module to generate an amount of electrical current required for corresponding operating conditions of the locomotive. A cooling system cools the at least one fuel cell power module in response to the amount of current being generated.
