Patent ID: 7521147

Claim:
A fuel cell, comprising: an electrolytic membrane layer provided with a front face and a rear face; a first metallic current collector layer having a plurality of transverse passages, the first current collector layer arranged on and in direct contact with the front face of the electrolytic membrane; a first electrode layer comprising a catalytic element deposited over the first current collector layer and the front face of the electrolytic membrane, wherein the first electrode layer: fills in the transverse passages of the first current collector layer and is in direct contact with the electrolytic membrane through the transverse passages, and covers the first current collector layer so that the first current collector layer is between the front face of the electrolytic membrane and the first electrode layer; a second metallic current collector layer having a plurality of transverse passages, the second current collector layer arranged on and in direct contact with the rear face of the electrolytic membrane; and a second electrode layer comprising a catalytic element deposited over the second current collector layer and the rear face of the electrolytic membrane, wherein the second electrode layer: fills in the transverse passages of the second current collector layer and is in direct contact with the electrolytic membrane through the transverse passages, and covers the second current collector layer so that the second current collector layer is between the rear face of the electrolytic membrane and the second electrode layer.
