(FR) ALLIAGE D'ACIER INOXYDABLE POUR PLAQUES BIPOLAIRES
Abstract: front page image
(EN)An improved bipolar plate stainless steel alloy comprises, in weight percent, about 20% to about 30% chromium, about 10% to about 25% nickel, about 1% to about 9 % molybdenum, and up to about 4% copper, where the weight percentage of chromium plus nickel plus molybdenum is greater than about 51 percent. The weight percentage of chromium plus molybdenum may be greater than about 1.66 times the weight percentage of nickel. In addition, the ratio of chromium equivalents to nickel equivalents may be greater than about 1.66.
(FR)L'invention porte sur un alliage d'acier inoxydable pour plaques bipolaires comportant en pourcentage pondéral: d'environ 20 % à environ 30 % de chrome, d'environ 10 % à environ 25 % de nickel, d'environ 1 % à environ 9 % de molybdène, et jusqu'à environ 4 % de cuivre, et dans lequel le pourcentage en poids de chrome plus celui de molybdène est supérieur à environ 51 % tout en étant supérieur à 1,66 fois celui de nickel, et dans lequel le rapport des équivalents chrome aux équivalents nickel peut être supérieur à environ 1,66.
