PhD Works: "Aging-Tolerant Control in PEMFC Fuel Cell Systems"

Abstract : 

The work presented in this thesis focuses on achieving aging-tolerant control for a proton exchange membrane fuel cell system (PEMFC). In order to achieve this goal, supervision tools, including the monitoring of critical variables, the state of health evaluation and the prediction of the future state are studied and realized. The information collected are used to adapt the system control strategy. The priority of the monitoring system developed is to ensure the energy supply required by the user, while ensuring minimal degradation of the fuel cell. The work consists on determining optimal temperature values, cathode and anode stoichiometry coefficients, and fuel cell current to provide the power required by the load, while extending the lifetime of the PEMFC. The proposed strategy avoids reversible damage and slows the agingrate of the components, while maintaining the value of the voltage in an optimal and low degrading operating range. This range of voltage variation was determined by studying the degradation mechanisms of PEMFC.
