Fuel cell power plant

   
   

A reformer (3) supplies a reformate gas to a fuel cell stack (4). The reformer (3) generates a reformate gas by reforming gaseous fuel vaporized by a vaporizer (2). When current supply from the fuel cell stack (4) to the electric motor (21) undergoes a sharp decrease, unnecessary consumption of gaseous fuel is prevented by closing a first valve (11) which supplies gaseous fuel from the vaporizer (2) to the reformer (3) and by opening a second valve (13) which returns gaseous fuel in the vaporizer (2) to the fuel tank (6).

Un reformador (3) provee un gas del reformate a un apilado de la célula de combustible (4). El reformador (3) genera un gas del reformate reformando el combustible gaseoso vaporizado por un vaporizador (2). Cuando la fuente actual del apilado de la célula de combustible (4) al motor eléctrico (21) experimenta una disminución aguda, la consumición innecesaria del combustible gaseoso es prevenida cerrando una primera válvula (11) que provea el combustible gaseoso del vaporizador (2) al reformador (3) y abriendo una segunda válvula (13) que vuelva el combustible gaseoso en el vaporizador (2) al depósito de gasolina (6).
