Approximate Reasoning Techniques in the Control of States of Operation of the PEM Fuel Cell

Abstract:

Among the different types of fuel cells, the proton-exchange membrane fuel cell (PEMFC) has attracted much interest as a power source for residential applications and electric vehicles. However, the development of new applications and the validation of new components of PEMFC require the characterization of their electrical response under certain conditions, both of operation (state variables) and power to be supplied (variation of electrical load), as well as the humidity degree of the membrane (operating state of the PEMFC considered Normal). Under this context, in this study, a set of specific processes based on approximate reasoning techniques have been designed and implemented for the dynamic control of the humidification of the polymeric membrane.
