Abstract
(EN)
The present invention provides a method for controlling a fuel cell system comprising: a fuel cell stack; a reformer for reforming raw fuel and feeding the raw fuel to the fuel cell stack; a fuel flow rate control unit for controlling the flow rate of the raw fuel fed to the reformer; an air feed tube for feeding oxygen to the raw fuel; and a combustor for mixing an anode exhaust gas and a cathode exhaust gas discharged from the fuel cell stack and causing the mixture to combust. In this method for controlling a fuel cell system, the current value for the current generated by the fuel cell stack and/or the oxygen feed amount of the oxygen fed from the air feed tube is detected, the composition of the anode exhaust gas is estimated on the basis of the current value and/or the oxygen feed amount, and the flow rate of the raw fuel is adjusted by means of the fuel flow rate control unit on the basis of the estimated composition of the anode exhaust gas, whereby the temperature of the combustor is controlled.

La présente invention concerne un procédé de commande d'un système de pile à combustible comprenant : un empilement de piles à combustible ; un reformeur pour reformer un combustible brut et alimenter l'empilement de piles à combustible avec le combustible brut ; une unité de commande de débit de combustible pour commander le débit du combustible brut introduit dans le reformeur ; un tube d'alimentation en air pour alimenter en oxygène le combustible brut ; et une chambre de combustion pour mélanger un gaz d'échappement d'anode et un gaz d'échappement de cathode déchargés à partir de l'empilement de piles à combustible et amener le mélange à brûler. Dans ce procédé de commande d'un système de pile à combustible, la valeur de courant pour le courant généré par l'empilement de piles à combustible et/ou la quantité d'alimentation en oxygène de l'oxygène introduit à partir du tube d'alimentation en air sont détectées, la composition du gaz d'échappement d'anode est estimée sur la base de la valeur de courant et/ou de la quantité d'alimentation en oxygène, et le débit du combustible brut est ajusté au moyen de l'unité de commande de débit de combustible sur la base de la composition estimée du gaz d'échappement d'anode, ce qui permet de commander la température de la chambre de combustion.

燃料電池スタックと、原燃料を改質して燃料電池スタックに供給する改質器と、改質器に供給する原燃料の流量を制御する燃料流量制御部と、原燃料に酸素を供給する空気供給管と、燃料電池スタックから排出されるカソード排ガスとアノード排ガスとを混合して燃焼させる燃焼器と、を備える燃料電池システムの制御方法が提供される。この燃料電池システムの制御方法では、燃料電池スタックで発電される電流値及び前記空気供給管から供給される酸素供給量の少なくとも一方を検出し、電流値及び酸素供給量の少なくとも一方に基づきアノード排ガスの組成を推定し、推定されたアノード排ガスの組成に基づき燃料流量制御部により原燃料の流量を調整することで燃焼器の温度を制御する。
