A simple approach to reaction control for auto‐thermal fuel‐reforming systems was proposed and examined. The amount of air supplied to the fuel‐reforming system was chosen as the variable in the feedback (closed‐loop) control operation, and simply by varying the amount of air supplied, it was attempted to control and stabilize the temperature of the auto‐thermal reforming reaction. The amounts of other fuels and water were chosen from pre‐determined values by open‐loop operation. Since the feedback operation was limited to the air‐supply mechanism, it was expected that both the hardware structure of the system and its software configurations could be significantly simplified. The applicability of this simple feedback control operation was confirmed experimentally by using a methanol reformer of the direct‐injection type.
