For safety reasons, distributed natural gas is mixed with a strong scent known as the odorant. While typically sulfur‐containing molecules are used for this purpose, a novel sulfur‐free odorant (Gasodor TM S‐free TM ) has been developed and introduced into the marketplace. Our thermodynamic analysis and experimental results show that the reforming of methane over a Rh/Ce 0.2 Gd 0.8 O 1,95‐δ catalyst is unaffected by the addition of Gasodor TM S‐free TM . The odorant is converted completely in the reforming step, so no negative influence is expected in the subsequent process steps. Overall, the addition of Gasodor TM S‐free TM should not pose a problem when combined with fuel cell systems.
