The high-throughput calculation predicts that the Fe-based cubic ferromagnet Fe₃Si may exhibit a large anomalous Nernst effect (ANE). Here, we report our experimental observation of the large Nernst coefficient Syx~2 μV/K and the transverse thermoelectric coefficient -αyx ~ 3 Am⁻¹K⁻¹ for Fe₃Si polycrystal at room temperature. The large -αyx indicates that the large ANE originates from the intrinsic Berry curvature mechanism. The high Curie temperature of 840 K and the most abundant raw elements of Fe and Si make Fe₃Si a competitive candidate for Nernst thermoelectric generations.
