    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: An electrode catalyst for a fuel cell including a carbon-based carrier and an active metal supported in the carrier, for example, an electrode catalyst for a fuel cell includes a carrier and an active metal supported in the carrier, wherein the electrode catalyst has an X value of 95 to 100% in Equation 1. X(%)=(XPS measurement value)/(TGA measurement value)×100  [Equation 1] wherein, the XPS measurement value represents a quantitative amount of the active metal present on a surface of the electrode catalyst, the TGA measurement value represents the XPS measurement value using a monochromated Al Kα-ray, which is the quantitative amount of total active metal supported in the catalyst.
