Coordination of Converter and Fuel Cell Controllers

Abstract: Load following fuel cell systems depend on control of reactant flow and regulation of DC bus voltage during load (current) drawn from them. To this end, we model and analyze the dynamics of a fuel cell system equipped with a compressor and a DC-DC converter. We then employ model-based control techniques to tune two separate controllers for the compressor and the converter. We demonstrate that the lack of communication and coordination between the two controllers entails a severe tradeoff in achieving the stack… Show more

“…Furthermore, in medium and large systems, fuel cells are accompanied by components to condition the electrical power generated, and usually there is some type of energy storage, which results in hybrid generation systems. In these systems, the control of power flows plays a key role in optimising the process [93].…”
