Based on the rainbow approximation of Dyson-Schwinger equation and the assumption that the inverse dressed fermion propagator at finite chemical potential is analytic in the neighborhood of {mu}=0, A new method for calculating the dressed fermion propagator at finite chemical potential in QED{sub 3} is developed. From this the effects of the chemical potential on the critical number of the fermion flavors is evaluated.
