Abstract
(EN)
Provided is a fuel cell system (FCS) which acquires an operation state of the fuel cell (FC) and estimates the IV characteristic which shows the relationship between current and voltage in the fuel cell (FC). The fuel cell system (FCS) obtains at least one of the resistance overvoltage, the activation overvoltage, the current/voltage hysteresis, and the concentration overvoltage from the operation state of the fuel cell (FC) and estimates the IV characteristic in accordance with the obtained result.
(FR)
La présente invention se rapporte à un système de pile à combustible (FCS) qui acquiert un état de fonctionnement de la pile à combustible (FC) et qui estime la caractéristique IV qui montre la relation entre le courant et la tension dans la pile à combustible (FC). Le système de pile à combustible (FCS) obtient la surtension de résistance et/ou la surtension d'activation et/ou l'hystérésis courant/tension et/ou la surtension de concentration à partir de l'état de fonctionnement de la pile à combustible (FC) et il estime la caractéristique IV en fonction du résultat obtenu.
(JA)
 この燃料電池システムFCSは、燃料電池FCの運転状態を取得し、燃料電池FCにおける電流と電圧との関係を示すIV特性を推定するものであって、燃料電池FCの抵抗過電圧、活性化過電圧、電流・電圧ヒステリシス、及び濃度過電圧の少なくとも一つを燃料電池FCの運転状態より求め、その求めた結果に基づいてIV特性を推定するものである。
