摘要：
A new nonlinear governing equation is obtained for the dynamics of hydrogen concentration. Numerical solution of the equation allows us to describe evolution of localized disturbance of the hydrogen concentration and the significant influence of nonlinearity on the shape of localized waves of the hydrogen concentration.
