In order to understand the effect of different B-site partial substitution without the influence of calendar corrosion, the overall electrochemical performance of LaNi4.7M0.3(M=Ni,Co,Mn,Al) alloys were rapidly evaluated by means of a powder microelectrode technique (PME). The cell parameters of the alloys were also measured by XRD for a better understanding of the substitution effects. The study results show that the activation cycle is shortened by Mn partial substitution for Ni and prolonged by Co and Al partial substitution and reveal that the effect of the partial substitution of Ni improves the cycling performance in the order Co>Al>MnCo>Al>Mn and enhances the anti-electro-oxidation ability in the order Mn
