Abstract: A load-following fuel cell system for a grid system operating with a high penetration of intermittent renewable energy sources includes a baseload power generation module and a load-following power generation module. The baseload power generation module provides a baseload power to the grid system and includes a high-efficiency fuel cell system. The high-efficiency fuel cell system includes a topping module and a bottoming module. The topping module and the bottoming module are connected in series and the topping module provides an exhaust stream to the bottoming module. The load-following power generation module provides a load-following power to the grid system and includes an energy storage system that separates and stores hydrogen contained in the exhaust stream and a power generation system having one or more fuel cells. The power generation system receives the hydrogen from the energy storage system to provide the load-following power.

Abstract: A fuel cell system includes a fuel cell unit configured to generate an amount of electrical power for supply to a varying electrical load and a fuel cell controller configured to receive a first indication that the varying electrical load is at a local maximum within a predetermined period, and, in response, operate the fuel cell unit with an operational parameter having a first value such that the fuel cell unit produces a limited maximum amount of electrical power that is a predetermined percentage of a maximum rated power output of the fuel cell unit. The fuel cell controller is also configured to receive an indication that the varying electrical load has reduced, and, in response, operate the fuel cell unit with the operational parameter having a second value such that the fuel cell unit produces an amount of electrical power below the limited maximum amount of electrical power.
