Kohlematerialien auf der Basis von pyrolysiertem Polyacrylnitril für Brennstoffzellenkatoden mit schwefelsaurem Elektrolyten

Carbon materials based on pyrolysed polyacrylonitrile supported on an appropriate support were applied as oxygen electrodes in sulfuric acid. Study, in dependence of pyrolysis temperature and metal content of the support, of the decomposition of hydrogen peroxide at these catalysts and the electrocatalytic behavior of the electrodes. Examination of the change of physicochemical characteristics as a function of the parameters of the heat treatment process
