    摘要： The durability of a polymer electrolyte fuel cell is very significantly improved by using a tightening pressure of about 2 to 4 kgf/cm2 of area of electrode; or a tightening pressure of about 4 to 8 kgf/cm2 of contact area between electrode and separator plate; or by selecting a value not exceeding about 1.5 mS/cm2 for the short-circuit conductivity attributed to the DC resistance component in each unit cell; or by selecting a value not exceeding about 3 mA/cm2 for the hydrogen leak current per area of electrode of each MEA. Further, in a method of manufacturing or an inspection method for a polymer electrolyte fuel cell stack, fuel cells having high durability can be efficiently manufactured by removing such MEAs or unit cells using such MEAs or such cell stacks having short-circuit conductivity values and/or hydrogen leak current values exceeding predetermined values, respectively.

    摘要： A polymer electrolyte fuel cell is provided with a conductive separator having one or more gas flow channels for supplying and exhausting a gas to and from an electrode of the fuel cell. The gas flow channels are connected to and in fluid communication with an inlet manifold on the separator. The cell also includes a gas supply connection in fluid communication with the inlet manifold of the separator. Water accumulation in the cell can be advantageously reduced by configuring the connections to the inlet manifold so that the lowermost part of any gas flow channel connections with the inlet manifold is above the uppermost part of the gas supply connection to the inlet manifold.
