A solid oxide fuel cell (SOFC) was developed for the direct utilization of dry glycerol to produce electricity at 800 °C. A state‐of‐art SOFC anode was covered by a thin (<10 μm) electrocatalyst layer based on a Ni‐modified perovskite and ceria. This electrocatalyst layer worked as an internal integrated fuel processor to convert glycerol in syngas. A performance of about 850 mW cm −2 @ 0.6 V was achieved with dry glycerol. A life time test of 160 hrs showed no relevant occurrence of carbon deposits. The developed approach can provide a practical route to achieve effective fuel flexibility in SOFCs.
