摘要:
A method of making a planar solid oxide fuel cell is described involving: (1) sintering at least an electrolyte layer; (2) juxtaposing one of a sintered anode or cathode layer with a metal substrate, with a bonding agent therebetween; and (3) applying heat to bond the juxtaposed anode or cathode layer to the metal substrate; where the anode and cathode layers are each sintered, together or independently, simultaneously with sintering the electrolyte layer, simultaneously with applying heat to bond the ceramic fuel cell element to the metal substrate, or in one or more separate sintering steps.
摘要:
Solid-oxide fuel cells include an electrolyte and an anode electrically coupled to a first surface of the electrolyte. A cathode is provided, which is electrically coupled to a second surface of the electrolyte. The cathode includes a porous backbone having a porosity in a range from about 20% to about 70%. The porous backbone contains a mixed ionic-electronic conductor (MIEC) of a first material infiltrated with an oxygen-reducing catalyst of a second material different from the first material.
