Abstract: A close-end fuel cell and an anode bipolar plate thereof are provided. The anode bipolar plate includes an airtight conductive frame and a conductive porous substrate disposed within the airtight conductive frame. In the airtight conductive frame, an edge of a first side has a fuel inlet, and an edge of a second side has a fuel outlet. The conductive porous substrate has at least one flow channel, where a first end of the flow channel communicates with the fuel inlet, a second end of the flow channel communicates with the fuel outlet. The flow channel is provided with a blocking part near the fuel inlet to divide the flow channel into two areas.

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.
