Abstract
Fuel cells which have a solid-oxide, thin film electrolyte and thin film cermet air and fuel electrodes. Processes for manufacturing thin film fuel cells in which air electrode, electrolyte, and fuel electrode films are deposited on a porous refractory substrate by magnetron sputtering.
Claims9
A fuel cell comprising:
- a yttria-stabilized zirconia electrolyte;
- a cermet fuel electrode comprising a yttria-stabilized zirconia on and in intimate contact with one side of said electrolyte;
- and
- a cermet air electrode on and in intimate contact with the other side of the electrolyte, the air electrode cermet having the nominal formula Ag.sub.l-f YSZ.sub.f, where f is volume fraction and ranges from about 0.5 to about 0.95.
