    Lógica borrosa para la estimación de estados críticos de una pila de combustible PEM
    (Universidad de Cuenca, 2014) Agila, Wilton E.; Huilcapi, Victor M.; Universidad de Cuenca; Dirección de Investigación de la Universidad de Cuenca; DIUC
    The real time determination of the critical states of operation of the fuel cell proton exchange membrane (acronym in English, PEM) is one of the main challenges for the control systems of PEM fuel cells. In this paper, the development and implementation of a non-invasive low cost method based on fuzzy decision techniques to estimate the critical states of operation of the PEM fuel cell is presented. The estimation is performed by perturbations of the state of operation of PEM fuel cell and the subsequent analysis of the temporal evolution of the voltage generated by the cell. The implementation of this stimulation-perceived technique of the state of fuel cell for the detection of critical states is a novelty and a step towards autonomous control in optimal operation of PEM fuel cells.
