Title:
固体酸化物形燃料電池用アノード
Document Type and Number:
Japanese Patent JP7075368
Kind Code:
B2
Abstract:
To provide a novel anode for a solid oxide fuel cell, which can suppress the increase in contact resistance owing to oxidation of an anode surface.SOLUTION: An anode for a solid oxide fuel cell comprises: a diffusion layer; a current-collecting layer formed on a current collector-side surface of the diffusion layer; and an active layer formed on an electrolyte-side surface of the diffusion layer. The diffusion layer is composed of a cermet (A) containing Ni particles (A) and electrolyte particles (A) made of yttria-stabilized zirconia. The current-collecting layer is composed of a cermet (B) containing Ni particles (B) and electrolyte particles (B) made of a composite oxide (YCZ) of Y2O3, CeO2 and ZrO2. The active layer is formed from a cermet (C) containing Ni particles (C) and electrolyte particles (C) of solid oxide.SELECTED DRAWING: Figure 4
