espanolDebido a la importancia a escala mundial de la escasez de energia y los efectos del cambio climatico estan emergiendo alternativas a las fuentes de energia clasicas como los combustibles fosiles y las centrales de energia nuclear de fusion. En este contexto se encuadran las tecnicas de “combined heat and power" como una posible solucion debido a su capacidad para generar energia electrica y termica de manera mas eficiente que los metodos convencionales. Respecto a esto, las pilas de combustible de alta temperatura con membrana de intercambio de protones permiten implementar sistemas de “combined heat and power" ademas de tratarse de una tecnologia eficiente y con menor impacto en la produccion de gases de efecto invernadero. En este articulo se describe un sistema de gestion de energia para un modelo simple basado en una pila de combustible usando control predictivo. Para ello se presentan las caracteristicas de la pila y su contribucion a la solucion de la problematica energetica actual en primer termino. Posteriormente, se describe una modelizacion y control de bajo nivel de la pila y sus subsistemas de generacion de calor y electricidad y, finalmente, un problema de control predictivo es propuesto como un metodo de gestion del calor y energia electrica que cumpla una determinada demanda residencial. EnglishDue to energy shortage and climate change e_ects world-wide, several alternatives to classical energy sources such as fossil fuels and nuclear fission power plants have arisen. In this context, combined heat and power appear as one of the possible solutions because of its ability to generate electrical and thermal energy more efficiently than conventional methods. Regarding this, high temperature proton exchange fuel cells enable the implementation of combined heat and power systems and have a lesser impact in the production of green- house effect gases to the one by conventional energy sources. In this article, an energy management system for a fuel-cell-based simple model controlled using predictive control is detailed. First of all, fuel cell characteristics as well as its contribution to the solution of the current energy problem are presented. Later on, modeling and low level control of the fuel cell and its heat and electricity generation subsystems are described and, finally, the proposed model predictive control problem is shown as a way to manage heat and electrical energy to fulfil a concrete residential demand.
