Catalytic activity of Ni-YSZ-CeO_2 anode for the steam reforming of methane in a direct internal-reforming solid oxide fuel cell

摘要

As one of the key technologies in the development of a direct internal-reformating solid oxide fuel cell, catalytic activity an stability of a Ni-YSZ-CeO_2 anode on a zirconia electrolyte for the steam reforming of methane was investigated by experiments using a differential duel Cell reactor. The effects of the partial pressure of CH_4, H_2O and H_2, and temperature as well as the electrochemical oxidation on the Catalytic activity were analyzed.
