Device and process for the control of the quantities of air, steam and fuel vapor injected into a reformer of an on-board fuel cell system

摘要

The electronic control unit (10) with an estimator (15) having the gas rates at the exit of the auto-thermal reforming (3) from the input data comprises the rate of: air supply flow; water vapor supply flow; fuel supply flow; and the inlet temperature of gases of the reformer. The exit temperature and the pressure of gases of the adiabatic reformer are estimated by the estimator. The concentrations and the temperature of the gases at the exit of the reformer are measured by concentration sensor and temperature gauge. An independent claim is also included for a method using the above device.
