In this paper, the use of an adaptive technique aimed at controlling a polymeric electrolyte membrane fuel cell is introduced. It is demonstrated that a hill climbing-based method, acting on the compressor speed and/or the cathode back-pressure valve, allows to better take into account the effect of exogenous variables on stack performance. Particularly, the proposed technique has proven to perform better than classical feedforward/feedback approaches when well known aging mechanisms deteriorate cell efficiency. Numerical results based on experimentally derived models confirm the potential of the proposed control method and its intrinsic reliability

Abstract
In this paper, the use of an adaptive technique aimed at controlling a polymeric electrolyte membrane fuel cell is introduced. It is demonstrated that a hill climbing-based method, acting on the compressor speed and/or the cathode back-pressure valve, allows to better take into account the effect of exogenous variables on stack performance. Particularly, the proposed technique has proven to perform better than classical feedforward/feedback approaches when well known aging mechanisms deteriorate cell efficiency. Numerical results based on experimentally derived models confirm the potential of the proposed control method and its intrinsic reliabilityI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
