    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 direct liquid fuel cell and a method and an apparatus for controlling fuel concentration therein is provided. Fuel cell output current density is sensed to determine if it becomes lowered by more than a certain magnitude and is maintained for a constant time. Fuel cell output voltage is sensed from an initial output voltage just before a point in time when the current density is lowered, to a output voltage, the new output voltage being increased as the current density is lowered and being then maintained at a new level. The new output voltage is compared with a transient voltage sensed between the initial output voltage and the new output voltage. If the transient voltage is equal to or less than the new output voltage, the fuel concentration in a liquid fuel supplied to the fuel cell stack is increased.
