Fuel cell system

Abstract

Fuel cell system (100) with a first fuel cell stack (11) and a second fuel cell stack (12) and an anode system, the anode system comprising: • a first supply line (21) opening into the first fuel cell stack (11) • a second supply line (22) opening into the second fuel cell stack (12) • a first jet pump (27) arranged in the first supply line (21) and dividing the first supply line (21) into a front section (31) and a rear section (32) • a first metering valve (36) arranged in the front section of the first supply line (21) • a second jet pump (28) arranged in the second supply line (22) and dividing the second supply line (22) into a front section (32) and a rear section (34) • a second metering valve (37) arranged in the front section of the second supply line (32) • a Recirculation line (26) • exactly one recirculation pump (30),which is configured to supply anode exhaust gas from the first fuel cell stack (11) and the second fuel cell stack (12) to the first jet pump (27) and the second jet pump (28), wherein exactly one recirculation pump (30) is arranged in the recirculation line (26), a first outlet (24) connecting the first fuel cell stack (11) to the recirculation line (26), a second outlet (25) connecting the second fuel cell stack (12) to the recirculation line (26), and a control unit (500), wherein the first supply line (21) has a first geometry and the second supply line (22) has a second geometry such that the first geometry and the second geometry are each designed such that the pressure losses in the first supply line (21) and the second supply line (22) are substantially the same and are below 100 mbar.
