Abstract

L'invention concerne un système d'alimentation électrique qui permet un fonctionnement autonome, même si aucune énergie n'est fournie par un système électrique, et qui fournit de l'énergie électrique. Un système d'alimentation électrique selon un mode de réalisation possède un dispositif de génération d'hydrogène, un dispositif de stockage d'hydrogène, un dispositif de génération d'énergie électrique à pile à combustible et un dispositif de commande, et fournit de l'énergie électrique à une unité de charge. Le dispositif de génération d'hydrogène génère de l'hydrogène à l'aide d'énergie électrique générée par utilisation d'énergie naturelle. Le dispositif de stockage d'hydrogène stocke l'hydrogène généré par le dispositif de production d'hydrogène. Le dispositif de génération d'énergie électrique à pile à combustible génère de l'énergie électrique à l'aide de l'hydrogène stocké dans le dispositif de stockage d'hydrogène, et fournit à l'unité de charge l'énergie électrique ainsi générée. Le dispositif de commande commande le fonctionnement du système d'alimentation électrique en fonction de la quantité d'énergie électrique utilisée par l'unité de charge. Dans ce cas, en fonction d'une quantité d'hydrogène stocké dans le dispositif de stockage d'hydrogène, le dispositif de commande commande le fonctionnement du dispositif de génération d'hydrogène qui génère de l'hydrogène.
