We report measurements of the inverse squared magnetic penetration depth,$\lambda^{-2}(T)$, in Pr$_{2-x}$Ce$_{x}$CuO$_{4-\delta}$ ($0.115 \leq x \leq0.152$) superconducting films grown on SrTiO$_3$ (001) substrates coated with abuffer layer of insulating Pr$_{2}$CuO$_{4}$. $\lambda^{-2}(0)$, $T_c$ andnormal-state resistivities of these films indicate that they are clean andhomogeneous. Over a wide range of Ce doping, $0.124\leq x \leq 0.144$,$\lambda^{-2}(T)$ at low $T$ is flat: it changes by less than 0.15% over afactor of 3 change in $T$, indicating a gap in the superconducting density ofstates. Fits to the first 5% decrease in $\lambda^{-2}(T)$ produce values ofthe minimum superconducting gap in the range of $0.29\leq\Delta_{\rmmin}/k_BT_c\leq1.01$.Comment: 4 pages 5 figure
