Abstract

A solid oxide fuel cell (1) includes a first cell (10), a second cell (11) and an interconnector (7). The first cell (10) and the second cell (11) respectively include an anode (3) containing NiO and CaZrO 3 , a cathode (6), and a solid electrolyte layer (4) disposed between the anode (3) and the cathode (6). The interconnector (7) is connected to the current collector (8) of the first cell (10) and the anode (3) of the second cell (11). The interconnector (7) contains LaCaCrO 3 . The molar ratio of Ca to Zr in the anode (3) is greater than 1.0. As a result, it is assumed that less Ca diffuses from the interconnector (7) towards the anode (3), and consequently the density of the interconnector (7) remains high.
