Disclosed are a conductive sintered body capable of effectively suppressing reduction expansion, a conductive member for fuel cells, a fuel-cell cell, and a fuel cell. Specifically disclosed is a conductive sintered body containing a first complex oxide phase (59) of a lanthanum chromite and a second complex oxide phase (55) of Mg and Ni. In this conductive sintered body, Ni (57) is deposited around the second complex oxide phase (55). Such a conductive sintered body is used for fuel cells. Also disclosed is a conductive member for fuel cells which is used as an interconnector (35) of a fuel cell (30) which comprises a solid electrolyte layer (33) held between a fuel electrode layer (32) and an oxygen electrode layer (34), and the interconnector (35) connected to the fuel electrode (32).
L'invention concerne un corps fritté conducteur capable de supprimer de manière efficace toute expansion et réduction, un élément conducteur pour pile à combustible, une cellule de pile à combustible, et une pile à combustible. L'invention concerne en particulier un corps fritté conducteur contenant une première phase oxyde complexe (59) d'un chromite de lanthane et une seconde phase oxyde complexe (55) de Mg et Ni. Dans ce corps fritté conducteur, du Ni (57) est déposé autour de la seconde phase oxyde complexe (55). Un tel corps fritté conducteur sert aux piles à combustible. L'invention concerne également un élément conducteur pour piles à combustible que l'on utilise comme interconnecteur (35) d'une pile à combustible (30) comprenant une couche électrolytique solide (33) maintenue entre une couche d'électrode à combustible (32) et une couche d'électrode oxygène (34), l'interconnecteur (35) étant connecté à l'électrode à combustible (32).
