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： The temperature of cooling fluid in an inlet side manifold is increased during power generation by influence of the temperature of heat generation sections of cells. This causes variation in temperature among unit cells in a fuel cell stack, causing flooding and variation in output voltage. The invention provides a fuel cell in which an increase in temperature of cooling fluid in an inlet side manifold is suppressed, and that has an excellent durability and a stable output voltage. The fuel cell has flow paths for cooling fluid in cathode side separator plates and anode side separator plates, the flow paths connecting an inlet side manifold and an outlet side manifold for cooling fluid. Each of the flow paths for cooling fluid includes a first cooling section for cooling a heat generation section, that is, an area corresponding to a cathode or an anode, and a second cooling section located between the first cooling section and the inlet side manifold for cooling fluid.
