摘要:
In a content reproduction apparatus according to the present invention, for example, a content usage time indicating a usage permitted time of content is set for the content, and a content reproduction management unit 811 manages a usage state and a rewind limit position of the content. Here, the rewind limit position is a position which indicates that the content cannot be reproduced till the end in the case where a user executes a rewind operation. For example, in the case where the user attempts to execute the rewind operation on the part that is in front of the rewind limit position, the content management unit 811 notifies the user of a warning message in advance.

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.
