DISPOSITIF ET PROCEDE DE COMMANDE D'UNE QUANTITE DE CARBURANT INJECTEE DANS UN REFORMEUR DE SYSTEME DE PILE A COMBUSTIBLE EMBARQUE A BORD D'UN VEHICULE AUTOMOBILE

摘要

The device has an air compression group (3) to supply air to a fuel cell (1) and an electronic control unit (4). The unit (4) has a hydrogen flow estimator (8) at output of a reformer (2) for estimating the hydrogen flow from input parameters including the data delivered to the cell or supplied by the cell. The unit (4) has control units (10) to control the quantity of fuel injected in the reformer. An independent claim is also included for a process to control a quantity of fuel injected in a reformer of a fuel cell system embarked on a motor vehicle.
