... 1,269,437. Fuel cells. VARTA A.G. 7 April, 1970 [11 April, 1969], No. 16496/70. Heading H1B. A fuel cell battery having hydrogen electrodes containing as catalyst a base metal of large effective surface area, and oxygen electrodes containing a substance which is capable of catalysing the electrochemical activation of hydrogen, is rapidly brought into operation by supplying both electrodes with gaseous hydrogen and short-circuiting the battery when the oxygen electrodes have attained the reversible hydrogen potential, by electrically connecting the hydrogen electrodes to the oxygen electrodes, until the hydrogen electrodes have attained the reversible hydrogen potential, whereafter the oxygen electrodes are separated from the hydrogen supply and connected to an oxygen supply. The oxygen electrode may comprise a supporting structure of carbonyl nickel and/or carbonyl iron and the base metal catalyst may be Raney-nickel, Raney-iron or Raney-cobalt. The oxygen electrode of one cell may be electrically ...
