Dynamical model of coupled electrode BZ reaction system is established based on FKN mechanism and Oregonator model.Under certain conditions,the effect of electrode current on BZ electrochemical reaction system is discussed.By means of stability analysis of three-variable system,limit cycle oscillatory regime of the electrode reaction phase is calculated numerically.It turns out that limit cycle oscillation can appear in electrode phase under a fixed current when the bulk phase is at a steady state.Meanwhile,external electrode current can lead to non-synchronization of bulk phase and electrode reaction phase.
