Patent ID: 7993794

Claim:
A fuel cell comprising: a membrane electrode assembly formed by a successive stacking of an anode, an electrolytic membrane and a cathode, the successive stacking being sandwiched between an anodic current collector in direct contact with the anode and a cathodic current collector in direct contact with the cathode, wherein the cathodic current collector is formed by a thin layer comprising at least one transverse passage, and a humidity regulation element formed over the cathodic current collector, the humidity regulation element comprising: a hydrophilic element comprising a first face and a second face, at least a part of the hydrophilic element being contained within at least one transverse passage of the cathodic current collector such that the first face of the hydrophilic element directly contacts an outer surface of the cathode, and a hydrophobic element over the second face of the hydrophilic element, wherein the hydrophobic element comprises at least one through opening exposing an area of the second face of the hydrophilic element, and wherein the at least one through opening is arranged above the transverse passage of the cathodic current collector.
