The Back Cover features prototypes of anode‐metal‐free and completely metal‐free anion exchange membrane fuel cells. The fuel cells are powered by the carbohydrazide oxidation reaction over 3D graphene as anode catalyst and nitrogen‐doped carbon nanotubes as cathode, generating a high peak power density. The average electron number electrochemically extracted from one carbohydrazide molecule is 4.9, indicating the existence of CN bond activation, which is a key factor contributing to high fuel utilization efficiency. These results open a new research arena for exploring the electrocatalytic properties of advanced nanocarbon materials and developing inexpensive fuel cells. More details can be found in the Communication by Qi et al. on page 1147 (DOI: 10.1002/cssc.201403032 ).
