Abstract
A fuel cell system is provided, comprising a cell unit capable of gas exhausting. The cell unit comprises an anode current collector and a cathode current collector. A membrane electrode assembly (MEA) is interposed between the anode current collector and the cathode current collector. A frame is formed to surround the MEA, the anode current collector, and the cathode current collector. A hydrophilic gas-blocking layer is disposed adjacent to an anode side of the MEA, underlying the MEA and the frame. A hydrophobic gas-penetrating layer is disposed under the hydrophilic gas-blocking layer. At least one gas exhaust is disposed in the frame, exposing a part of the hydrophilic gas-blocking layer and contacting the area surrounding adjacent to the cell unit for exhausting a gas produced by the MEA from the cell unit.
