✦ Synopsis

The internal surface areas of the electrodes were between 20 and 30 m2/g and were determined by adynamicBETrneth~d[~] before and after the electrochemical measurements. The current strengths were considered constant if their values varied by less than 3% over a period of 5 hours.

By using a slightlydifferent technique for the fabrication of electrodes and the same method of preparationof WCmuch thinner electrodes (ca. 0.2 mm) can be prepared having a large surface area and almost the same activity.
