US 2008/0176128 A1 · FUEL CELL

Abstract

A fuel cell including a membrane electrode assembly (MEA), an anode current collector, a cathode current collector and a water transport layer is provided. The MEA includes an anode layer, a cathode layer, and an electrolyte layer disposed between the anode layer and the cathode layer. The anode current collector is in contact with the anode layer. The cathode current collector is in contact with the cathode layer to dispose the MEA between the anode current collector and the cathode current collector, and the cathode current collector has a plurality of first openings. The water transport layer is attached on the cathode current collector and includes a capillary material and a plurality of second openings corresponding to the first openings of the cathode current collector.
