Estimating the term…
The invention relates to a method (100) for operating a fuel cell system (200), the method (100) comprising: a first determination step (101), in which a hydrogen concentration supplied to a fuel cell stack (203) of the fuel cell system (200) by means of an inlet valve (209) of the fuel cell system (200) is determined, a second determination step (103), in which a nitrogen volume flow flowing through the fuel cell stack (203) is determined, and an adjustment step (105), in which a rotational speed of a recirculation fan (205) of the fuel cell system (200) is adjusted on the basis of the determined hydrogen concentration and the determined nitrogen volume flow. The invention also relates to a fuel cell system (200) and a to computer program product according to the appended claims.
A method (100) for operating a fuel cell system (200), wherein the method (100) comprises:
A fuel cell system (200) comprising an electronic controller (201),
A non-transitory, computer-readable medium containing instructions which, when executed on a computer, configures the computer to determine a hydrogen concentration supplied to a fuel cell stack (203) of the fuel cell system (200) by means of an inlet valve (209) of the fuel cell system (200), determine a nitrogen volume flow flowing through the fuel cell stack (203), and adjust a rotational speed of a recirculation fan (205) of the fuel cell system (200) on the basis of the determined hydrogen concentration and the determined nitrogen volume flow.
