Abstract: front page image
(EN)The present invention relates to a sealed fuel cell system. According to an embodiment of the present invention, the sealed fuel cell system comprises: a main fuel cell which produces electricity by reacting fuel with oxygen; a supply means which supplies a gas including the fuel and the oxygen to the main fuel cell; a recirculation means which recirculates the gas, which includes the oxygen and hydrogen that are discharged from the main fuel cell, to the main fuel cell; a sensing means which senses a plurality of cell voltages that constitute the main fuel cell; a reproduction means which is selectively communicated with one side of the main fuel cell and eliminates moisture and impurities from the inside of the main fuel cell; and a controlling means which controls the operation of the supply means, the recirculation means, the sensing means, and the reproduction means. The reproduction means comprises: a reproduction pipe which guides the flowing direction of the gas that includes the hydrogen and the oxygen passing through the recirculation means; a reproduction valve which selectively shields the reproduction pipe; a regenerative fuel cell which generates water by reacting the gas including the hydrogen and the oxygen provided from the reproduction pipe inside the regenerative fuel cell; and a water gathering unit which gathers water generated from the regenerative fuel cell. According to the present invention, the risk of explosion caused by the discharge of hydrogen is resolved, and the generation efficiency and durability of the main fuel cell can be improved because moisture and impurities are eliminated.
(FR)La présente invention concerne un système de pile à combustible scellé. Selon un mode de réalisation de la présente invention, le système de pile à combustible scellé comprend: une pile à combustible principale qui produit de l'électricité par une réaction entre le combustible et l'oxygène; un moyen d'alimentation qui fournit à la pile à combustible principale un gaz comprenant le combustible et l'oxygène; un moyen de recirculation qui met en recirculation, vers la pile à combustible principale, le gaz incluant l'oxygène et l'hydrogène qui sont libérés par la pile à combustible principale; un moyen de détection qui détecte une pluralité de tensions de pile qui constituent la pile à combustible principale; un moyen de reproduction qui est sélectivement communiqué à un côté de la pile à combustible principale et élimine l'humidité et les impuretés se trouvant à l'intérieur de la pile à combustible principale; et un moyen de commande qui commande le fonctionnement du moyen d'alimentation, du moyen de recirculation, du moyen de détection et du moyen de reproduction. Le moyen de reproduction comprend: un tuyau de reproduction qui guide la direction d'écoulement du gaz qui inclut l'hydrogène et l'oxygène traversant le moyen de recirculation; un clapet de reproduction qui masque sélectivement le tuyau de reproduction; une pile à combustible réversible qui génère de l'eau par réaction du gaz incluant l'hydrogène et l'oxygène distribué par le tuyau de reproduction à l'intérieur de la pile à combustible réversible; et une unité de récupération d'eau qui récupère l'eau produite par la pile à combustible réversible. Selon la présente invention, le risque d'explosion provoqué par la libération d'hydrogène est résolu et l'efficacité de génération et la durabilité de la pile à combustible principale peuvent être améliorées du fait de l'élimination de l'humidité et des impuretés.
