    Abstract: An air-cooling fuel cell stack includes fuel cells, wherein each of the fuel cells includes an anode bipolar plate, a cathode bipolar plate, a membrane electrode assembly (MEA) between the anode and cathode bipolar plates, and an anode sealing member. The MEA includes an anode side structure, a cathode side structure, and an ion conductive membrane (ICM), and the ICM is sandwiched between the anode side structure and the cathode side structure. The anode sealing member is disposed at a periphery of the anode side structure and sandwiched by the anode bipolar plate and the ICM. The anode sealing member includes a first sealing material and a second sealing material, a Shore hardness of the first sealing material is different from that of the second sealing material, and an arrangement direction of the first and second sealing materials is perpendicular to a compression direction of the plurality of fuel cells.
