A [NiIr]‐based catalyst turns the table on CO poisoning by exploiting the gas as a fuel. The system is able to act as a H 2 oxidizing catalyst at low pH and as a CO oxidizing catalyst at high pH. At pH 7, there is a crossover where both oxidations are catalyzed simultaneously. In their Communication on page 9723 ff., S. Ogo et al. report a proof‐of‐concept fuel cell that functioned on a 50:50 supply of H 2 and CO. The double function is depicted above as a two‐headed bird.
