Patent ID: 8298722

Claim:
A fuel cell, comprising: a substrate layer, comprising a first surface and a second surface, wherein the first surface is opposite to the second surface; a first electrode, formed on the first surface; a second electrode, formed on the second surface; a first chamber layer, disposed on the first electrode, wherein the first chamber layer comprises a first flow passage and a first fuel chamber, the first flow passage is connected to the first fuel chamber, and a first gas passes the first flow passage, enters the first fuel chamber and contacts the first electrode; and a second chamber layer, disposed on the second electrode, wherein the second chamber layer comprises a second flow passage and a second fuel chamber, the second flow passage is connected to the second fuel chamber, and a second gas passes the second flow passage, enters the second fuel chamber and contacts the second electrode, wherein the substrate layer, the first electrode, the second electrode, the first chamber layer and the second chamber layer are integrally formed by co-firing, wherein the first chamber layer further comprises a first wire hole, the second chamber further comprises a second wire hole, the first wire hole is connected to the first fuel chamber allowing the first gas to flow in the first wire hole, and the second wire hole is connected to the second fuel chamber allowing the second gas to flow in the second wire hole.
