Abstract
An excellent stable hydrogen electrode of low polarization is provided which comprises Raney nickel catalyst containing about 0.2-2% by weight of chromium. Such hydrogen electrode is produced safely without spontaneous ignition of the catalyst by mixing and kneading a powder of the catalyst and a suspension liquid of polytetrafluoroethylene (PTFE) while dehydrating at low temperature.
