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： In a polymer electrolyte fuel cell of the present invention, at least one of electrodes comprises conductive carbon carrying a platinum group metal catalyst, conductive carbon carrying no catalyst metal and a hydrogen ion-conductive polymer electrolyte. The preferable amount of the conductive carbon carrying no catalyst metal is equivalent to 5 to 50 wt % of the conductive carbon carrying the catalyst metal. Incorporation of the conductive carbon carrying no catalyst metal to the catalyst layer enables reduction in potential concentration on part of electron conduction channels in an electrode, whereby an electrode for a polymer electrolyte fuel cell having an excellent life characteristic can be provided.

摘要： The electro-migration of electrode metal takes place under an elevated temperature condition in amorphous silicon devices having conventional PI-type, NI-type, or PIN-type hydrogenated amorphous silicon layered structures, which substantially degrades the electrical characteristics of the devices. This problem is solved by forming a chemically inactive layer consisting mainly of amorphous silicon oxide on the surface of amorphous silicon layer by an aqueous washing and drying process, to establish electrical contacts through the chemically inactive layer between the hydrogenated amorphous silicon layer and either a collector electrode or a transparent electrode. This structure not only prevents such electromigration of electrode metal, but it also allows a greater freedom for choosing a material for the collector electrode.
