Title
(EN) FUEL CELL SYSTEM
(FR) SYSTÈME DE PILES À COMBUSTIBLE
Abstract
(EN)
A fuel cell system includes a fuel cell stack generating electric power through an electrochemical reaction between hydrogen and oxygen, a fuel process unit that reforms a power generation fuel into a reformed gas containing hydrogen and is connected to the fuel cell stack to supply the reformed gas to the fuel cell stack, an oxygen supply unit supplying oxygen to the fuel cell stack, a residual reformed gas discharge pipe that is installed between the fuel cell stack and the fuel process unit to allow residual reformed gas that is not consumed in the fuel cell stack to be returned to a combustor of the fuel process unit, and a heat absorption unit that is installed on the residual reformed gas discharge pipe to dissipate heat contained in the residual reformed gas. According to the fuel cell system of the present invention, internal temperatures of the reforming reactor of the fuel process unit and the combustor can be uniformly maintained and the amount of power generation can stably increase while increasing an amount of the power generation fuel linearly or step by step.

Un système de piles à combustible inclut un module de piles à combustible générant de l'électricité par l'intermédiaire d'une réaction électrochimique entre hydrogène et oxygène, une unité de traitement de combustible qui reforme un combustible électro-générateur en un gaz reformé contenant de l'hydrogène et est connecté au module de piles à combustible pour fournir le gaz réformé au module de piles à combustible, une unité fournissant de l'oxygène fournissant l'oxygène au module de piles à combustible, un tube de décharge de gaz reformé résiduel qui est installé entre le module de piles à combustible et l'unité de traitement de combustible pour permettre que le gaz réformé résiduel qui n'est pas consumé dans le module de piles à combustible soit envoyé à une chambre de combustion de l'unité de traitement du combustible, et une unité d'absorption de la chaleur qui est installée sur le tube de décharge de gaz reformé résiduel pour dissiper la chaleur contenue dans le gaz reformé résiduel. Selon le système de piles à combustible de la présente invention, les températures internes du réacteur de reformage de l'unité de traitement du combustible et la chambre de combustion peuvent être entretenues uniformément et la quantité de production d'électricité peut augmenter stablement tout en augmentant une quantité du combustible électro-générateur de façon linéaire ou pas à pas.
