Abstract: The present invention addresses the problem of providing: a core-shell catalyst capable of achieving, when evaluated for a fuel cell, the catalytic activity anticipated from the catalyst activity value obtained using a rotating disc electrode (RDE); and a method for activating a core-shell catalyst in said manner. The present invention relates to a fuel cell catalyst, which is an electrode catalyst having a core-shell structure and is characterized in that at least 99% of the core member is covered by the shell member and the halogen content is not more than 5000 ppm. The present invention also relates to a method for activating said core-shell catalyst, the method comprising: a process for dispersing the core-shell catalyst in a dispersion solvent; a process for separating impurities from said core-shell catalyst by blowing a gas that has reducing properties or a mixed gas comprising same into said dispersion solvent; and a process for removing said impurities.

Abstract: A technology is provided that is capable of improving deterioration of a fuel cell due to non-stationary operation (startup/shutdown, fuel depletion). An anode-side catalyst composition comprising a catalyst having catalyst particles carried on electrically conductive material and an ion exchange resin, characterized in that the catalyst particle are formed of an alloy, of which oxygen reduction capability and water electrolysis are both lower than those of platinum, and which has hydrogen oxidation capability.

Abstract: An apparatus and method of recording a video format signal having a vertical blanking interval on a recording medium. The number of frames of the video format signal to be recorded on the recording medium is counted, and a first time code is generated such that one second corresponds to L-frames of the video format signal. The first time code is then incremented N-times within a predetermined period of the video formal signal, thereby obtaining a second time code representing the incremented first time code. The second time code is then inserted into the video blanking interval of the format signal, thereby producing a video format signal having a time code which is relatively close to the actual elapsed time of the signal.
