Title (EN) DC POWER SOURCE WITH FUEL CELL
(FR) SOURCE DE COURANT CONTINU AVEC PILE À COMBUSTIBLE
Abstract: front page image
(EN)A power source system (1) includes a fuel cell (40) and a battery (20) connected in parallel. A DC-DC converter (30) is connected to the battery (20) side. A maximum output ratio of the fuel cell (40) and the battery (20) is set in a range in which the output of the fuel cell falls within 65 to 80 % of the total output. Accordingly, electric power loss due to the DC-DC converter (30) is controlled, whereby a high energy efficiency can be achieved.
(FR)Un système de source de courant (1) inclut une pile à combustible (40) et une batterie (20) montées en parallèle. Un transformateur courant continu (30) est monté du côté de la batterie (20). Le rapport des sorties maximales de la pile à combustible (40) et de la batterie (20) s'établit dans une plage dans laquelle la sortie de la pile à combustible se place au niveau du 65% à 80% de la sortie totale. On arrive ainsi à limiter les pertes de courant électrique imputables au transformateur courant continu (30), ce qui permet un rendement énergétique élevé.
