    摘要: A fuel cell stack including membrane-electrode assemblies and separators formed between each of the membrane-electrode assemblies is disclosed. The membrane-electrode assemblies may each include an electrolyte membrane, an anode formed on a first surface of the electrolyte membrane, and a cathode formed on a second surface of the electrolyte membrane. Each of the separators may include an anode separator facing the anode and a cathode separator facing the cathode. Each of the separators may include at least two manifolds, a channel separated from the manifolds and facing either the anode or the cathode, and a connection channel fluidly connecting the manifold and the channel. The separator may also include a buffer protrusion system in the connection channel configured to disperse the flow of the fuel or the oxidant.

    摘要: A fuel cell stack configured to alleviate pressure and decrease the flow rate of at least one of a fuel and an oxidant is disclosed. The fuel cell stack includes a membrane-electrode assembly, an anode separator, a cathode separator and a filing member. The membrane-electrode assembly may include an electrolyte membrane, an anode formed on a first surface of the electrolyte membrane, and a cathode formed on a second surface of the electrolyte membrane. The anode separator may include a fuel channel, a fuel inlet manifold in fluid communication with the fuel channel, and a fuel outlet manifold in fluid communication with the fuel channel. The cathode separator may include an oxidant channel, an oxidant inlet manifold in fluid communication with the oxidant channel, and an oxidant outlet manifold in fluid communication with the oxidant channel. The filling member may be positioned within at least one of the fuel inlet manifold and the oxidant inlet manifold.

    摘要: A fuel cell stack includes membrane-electrode assemblies and separators that are closely disposed to both sides of the membrane-electrode assembly. Each membrane-electrode assembly includes an electrolyte membrane, an anode electrode that is formed on one surface of the electrolyte membrane, a cathode electrode that is formed on the other surface of the electrolyte membrane, and a protective layer formed at an oxidant inlet region where oxidant is first injected into the respective cathode electrode.
