    摘要： A hydrogen fuel cell unit is made from identical bipolar plates, each stamped from a single sheet of steel and coated with ta-C, the unit comprising, in order
    (i) a first bipolar plate having a front face and a rear face, the rear face being an anode in the unit,
    (ii) a first membrane electrode assembly,
    (iii) a second bipolar plate having a front face and a rear face, the front face being a cathode in the unit and the rear face being an anode in the unit,
    wherein the first membrane electrode assembly is between the first and second bipolar plates, and a flow path is provided between the rear face of the first bipolar plate and the first membrane electrode assembly for flow of hydrogen, and a flow path is provided between the front face of the second bipolar plate and the first membrane electrode assembly for flow of oxygen,
    (iv) a second membrane electrode assembly, and
    (v) a third bipolar plate having a front face and a rear face, the front face being a cathode in the unit,
    wherein the second membrane electrode assembly is between the second and third bipolar plates, and a flow path is provided between the rear face of the second bipolar plate and the second membrane electrode assembly for flow of hydrogen, and a flow path is provided between the front face of the third bipolar plate and the second membrane electrode assembly for flow of oxygen.

    摘要： A fuel cell device includes a housing (1) defining an inner space (100), a runner plate (2) disposed in the inner space (100), two electrode plates (3) disposed in the inner space (100) such that the runner plate (2) is stacked on and in contact with one of the electrode plates (3), and a proton exchange membrane (4) clamped between the electrode plates (3). The runner plate (2) includes a plurality of straight sections (21) arranged in two rows, and a plurality of connecting sections (22). Each two adjacent straight sections (21) define an opening (201) therebetween. The openings (201) in the two rows are staggered with respect to each other. Each two adjacent connecting sections (22) are connected to and cooperate with a common straight section (21) to define a drain channel (200) communicating with the opening (201) that aligns with the common straight section (21).
