Abstract

Un método para poner en marcha un sistema de celdas de combustible (100), el cual comprende un apilamiento de celdas de combustible (110), cuyo método comprende los pasos de: i) abrir una válvula de entrada del ánodo (153) para permitir que el combustible ingrese un volumen de ánodo del apilamiento de celdas de combustible (110); ii) activar un compresor de aire (133) en comunicacion fluida con una entrada de aire del cátodo (126) del apilamiento de celdas de combustible (110) para permitir que el aire ingrese un volumen de cátodo del apilamiento de celdas de combustible (110); iii) controlar la temperatura de la entrada (126) y/o salida (121) del cátodo; y iv) poner en funcionamiento un sistema de inyeccion de agua para inyectar agua en el volumen del cátodo una vez que la temperatura del fluido que pasa a través de la entrada y/o salida del cátodo exceda un nivel prefijado, en el cual una corriente extraída del apilamiento de celdas de combustible (110) está limitada para impedir que el voltaje medido a través de una o más celdas en el apilamiento de celdas de combustible (110) disminuya por debajo de un primer umbral de voltaje.
