Performance study of passive and active direct borohydride fuel cell employing a commercial Pd decorated Ni-Co/C anode catalyst

摘要

In this study, a new Pd decorated Ni-Co/C anode catalyst with remarkably high performance was introduced for using in direct borohydride fuel cell (DBFC) and compared to conventional 10 wt.% Pt/C anode catalyst. The activity and poisoning tolerance of both catalysts were investigated by electrochemical techniques in half-cell. The results indicated that the Pd decorated Ni-Co/C had higher activity compared to the 10 wt.% Pt/C in borohydride oxidation reaction (BOR). However, its poisoning tolerance was lower than 10 wt.% Pt/C during 200 cycles.
