    摘要： A polymer electrolyte fuel cell may include a stack of unit cells that each have a hydrogen-ion conductive polymer electrolyte membrane and an anode and a cathode sandwiching the polymer electrolyte membrane. Separators are provided between each two adjacent unit cells and include channels for supplying fuel and oxidant gas to the anode and the cathode. Anode side and cathode side current collector plates sandwich the stack of unit cells. The anode side current collector plate has a terminal section for a power output coupling and is located closer to an inlet-side manifold than to an outlet-side manifold for the fuel gas. The cathode side current collector plate has a terminal section for a power output coupling and is located closer to an inlet-side manifold than to an outlet-side manifold for the oxidant gas.

    摘要： A fuel cell having high operation performance and reliability is provided by optimizing the shape and properties of a gas diffusion layer and the dimensions of a gas flow channel. The fuel cell evenly supplies a reaction gas to the catalyst of a catalyst layer and promptly discharges excessive water generated therein. The gas diffusion layer of the MEA comprises a first section having a surface A coming in direct contact with a separator plate and a second section having a surface B facing the gas flow channel of the separator plate. The porosity of the first section is lower than the porosity of the second section, and the second section protrudes into the gas flow channel, which has sufficient width and depth for the protrusion of the gas diffusion layer, and the width of a rib formed by the gas flow channel is sufficiently narrow.

    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.
